ETHYL FORMATE

Ethyl formate is used as: a preservative and disinfectant, an acetone substitute, a solvent for cellulose acetate and nitrate, a larvicide and fungicide (for cereals, dried fruits, and tobacco), in organic synthesis, as a flavouring ingredient (in lemonades as well as essences), in the production of arrac and rum, and in the production of Estazolam (an anticonvulsant drug) (ACGIH, 1991; Ashford, 1994; Budavari, 1996; HSDB , 1998; Lewis, 1993).

FORMS

Available Grade of purity: 95+% (CHRIS , 1998).

SYNONYM EXPLANATION

AREGINAL is a mixture of ethyl formate and methyl formate (HSDB , 1998).

-CLINICAL EFFECTS

GENERAL CLINICAL EFFECTS

Ethyl formate is a mucous membrane irritant, which is less irritating but more strongly narcotic than methyl formate. No chronic effects have been seen in humans.

Ethyl formate is moderately toxic by ingestion and mildly toxic by skin contact and inhalation.

POTENTIAL HEALTH HAZARDS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 129 (ERG, 2004)

May cause toxic effects if inhaled or absorbed through skin.
Inhalation or contact with material may irritate or burn skin and eyes.
Fire will produce irritating, corrosive and/or toxic gases.
Vapors may cause dizziness or suffocation.
Runoff from fire control or dilution water may cause pollution.

-MEDICAL TREATMENT

LIFE SUPPORT

Support respiratory and cardiovascular function.

SUMMARY

FIRST AID - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 129 (ERG, 2004)

Move victim to fresh air.
Call 911 or emergency medical service.
Give artificial respiration if victim is not breathing.
Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes.
In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
Wash skin with soap and water.
Keep victim warm and quiet.
In case of burns, immediately cool affected skin for as long as possible with cold water. Do not remove clothing if adhering to skin.
Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed.
Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.

FIRST AID

FIRST AID

EYE EXPOSURE - Immediately wash the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately. Contact lenses should not be worn when working with this chemical.
DERMAL EXPOSURE - Immediately flush the contaminated skin with water. If this chemical penetrates the clothing, immediately remove the clothing and flush the skin with water. Get medical attention promptly.
INHALATION EXPOSURE - Move the exposed person to fresh air at once. If breathing has stopped, perform artificial respiration. Keep the affected person warm and at rest. Get medical attention as soon as possible.
ORAL EXPOSURE - If this chemical has been swallowed, get medical attention immediately.
TARGET ORGANS - Eyes, respiratory system, and CNS (National Institute for Occupational Safety and Health, 2007).

GENERAL -

Move victims of inhalation exposure from the toxic environment and administer 100% humidified supplemental oxygen with assisted ventilation as required. Exposed skin and eyes should be copiously flushed with water. Because of the potential for rapid onset of CNS depression or seizures with possible aspiration of gastric contents, EMESIS SHOULD NOT BE INDUCED. Cautious gastric lavage followed by administration of activated charcoal may be of benefit if the patient is seen soon after the exposure.

INHALATION EXPOSURE -

INHALATION: Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with an inhaled beta2-adrenergic agonist. Consider systemic corticosteroids in patients with significant bronchospasm.
If bronchospasm and wheezing occur, consider treatment with inhaled sympathomimetic agents.
ACUTE LUNG INJURY: Maintain ventilation and oxygenation and evaluate with frequent arterial blood gases and/or pulse oximetry monitoring. Early use of PEEP and mechanical ventilation may be needed.

DERMAL EXPOSURE -

DECONTAMINATION: Remove contaminated clothing and jewelry and place them in plastic bags. Wash exposed areas with soap and water for 10 to 15 minutes with gentle sponging to avoid skin breakdown. A physician may need to examine the area if irritation or pain persists (Burgess et al, 1999).
Treat dermal irritation or burns with standard topical therapy. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines.

EYE EXPOSURE -

DECONTAMINATION: Remove contact lenses and irrigate exposed eyes with copious amounts of room temperature 0.9% saline or water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist after 15 minutes of irrigation, the patient should be seen in a healthcare facility.

INGESTION EXPOSURE -

Because of the potential for gastrointestinal tract irritation and CNS depression, do NOT induce emesis.
Significant esophageal or gastrointestinal tract irritation or burns may occur following ingestion. The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation.
GASTRIC LAVAGE: Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Protect airway by placement in the head down left lateral decubitus position or by endotracheal intubation. Control any seizures first.

CONTRAINDICATIONS: Loss of airway protective reflexes or decreased level of consciousness in unintubated patients; following ingestion of corrosives; hydrocarbons (high aspiration potential); patients at risk of hemorrhage or gastrointestinal perforation; and trivial or non-toxic ingestion.

ACTIVATED CHARCOAL: Administer charcoal as a slurry (240 mL water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents, 25 to 50 g in children (1 to 12 years), and 1 g/kg in infants less than 1 year old.
Observe patients with ingestion carefully for the possible development of esophageal or gastrointestinal tract irritation or burns. If signs or symptoms of esophageal irritation or burns are present, consider endoscopy to determine the extent of injury.

-RANGE OF TOXICITY

MINIMUM LETHAL EXPOSURE

The minimum lethal human dose to this agent has not been delineated.

In humans, the probable lethal oral dose of ethyl formate is on the order of 0.5 to 5 mg/kg, or between 1 oz and 1 pint (1 lb) for a 70 kg (150 lb) individual (HSDB , 1998).

ANIMAL DATA

Cats exposed to 10,000 ppm for 75 minutes developed deep narcosis and died in 90 minutes. A 4-hour exposure to 8000 ppm was fatal in rats, but all survived 4 hours at 4000 ppm. Dogs died after 4 hours at 10,000 ppm (ACGIH, 1991).

MAXIMUM TOLERATED EXPOSURE

The maximum tolerated human exposure to this agent has not been delineated.

CONCENTRATION LEVEL

In humans, a concentration of 330 ppm ethyl formate produced slight eye irritation and rapidly increasing nasal irritation (ACGIH, 1991).

The category 'garments' may include totally encapsulating suits, splash suits, as well as other items (e.g., coveralls, jackets, and aprons). Specific manufacturers should be contacted to determine the features of available styles/models.
In addition to chemical resistance information, there are many critical variables in the selection of protective clothing which cannot be represented in this summary of the literature. Some factors to be considered in choosing protective clothing include, but are not limited to: overall clothing integrity, physical hazard resistance, durability, human factors, ease of decontamination, and cost. Overall clothing integrity refers to a specific design's ability to offer consistent protection for all clothing-covered areas of the body. Physical hazards include resisting the effects of abrasion, cuts, tears, and punctures. Human factors entail effects on wearer mobility, visibility, and hearing for garments; dexterity, tactility, and grip for gloves; ankle support and weight for footwear; and, any effect of the clothing on the function of the wearer. There are several variations in the design for gloves, garments, and footwear that affect these factors. Protective clothing must properly be sized and correctly fit the wearer to ensure its proper use and function.
As required in the U.S.A., protective clothing should be selected based on a risk assessment of the workplace. This risk assessment must account for the identification of existing as well as potential hazards and involve the recommendation of protective clothing appropriate for the identified hazards. Therefore, the recommendations in this section should not be used as the sole basis for decisions on choice of protective clothing, but rather should be used as a tool by qualified occupational health and safety professionals or other technically qualified persons in conjunction with a review of all mitigating factors. Consult the OSHA PPE Standard (29 CFR 1910.132 - 1910.138) for regulations and additional guidance regarding the selection and use of protective clothing and equipment. For general information on protective clothing selection, refer to the "PERSONAL PROTECTIVE EQUIPMENT - OSHA PUB 3077" document.
PROTECTIVE CLOTHING SELECTION

Determine the type of protective clothing item needed based on a risk assessment (e.g., gloves, garments, footwear).
For high risk situations, choose clothing that covers all parts of the body that may be exposed. In many cases, multiple clothing items will be required. Low risk situations may permit partial body protective clothing. Select protective clothing products that have reported chemical resistance data. High risk situations involving full body clothing or extended chemical contact often require permeation resistance data to determine the barrier effectiveness of materials used in the construction of clothing. Relatively low risk situations, where only splash or incidental exposure occur, may allow use of protective clothing based on degradation or penetration resistance data. Specifics on the interpretation of chemical resistance data are presented below.
Other factors must be considered in addition to chemical resistance. The selected chemical protective clothing item should offer the optimal combination of protection against identified hazards while allowing maximum function and comfort.

INTERPRETATION OF DEGRADATION RATINGS

Degradation refers to physical changes in a material as the result of chemical exposure. Degradation may become evident in visible changes, such as discoloration, swelling, delamination, deterioration, or disintegration. Degradation effects may also be measured by weight change or other changes in a material's physical properties (e.g., strength, elasticity, hardness).
Degradation resistance ratings are provided by manufacturers to rate the amount of degradation that occurs for a particular protective clothing material when contacted by a chemical. All degradation ratings are qualitative and include ratings, such as "EXCELLENT," "GOOD," "FAIR," "POOR," and "NOT RECOMMENDED." There is no standard test method for the measurement of chemical degradation resistance; therefore, manufacturer ratings may be based on different testing approaches. This makes comparison of degradation ratings between manufacturers unreliable.
The use of degradation resistance ratings alone to recommend protective clothing, particularly for high hazard situations, should be avoided. Degradation resistance testing does not directly assess the barrier quality of protective clothing, since materials can show relatively little degradation but still allow either permeation or penetration by a chemical. Degradation resistance ratings can be used to exclude protective clothing materials from consideration. Protective clothing materials with a "NOT RECOMMENDED" degradation resistance rating should never be used.
For some products, the rating "NO PENETRATION" is provided. This refers to penetration resistance test results that are based on a different procedure (American Society for Testing and Materials (ASTM) Standard Test Method F 903). Penetration resistance testing involves placing a material sample in a test cell, exposing the exterior side of the material to a chemical, and then observing the interior side of the material for visible signs of liquid penetration. Part of the test is conducted at an elevated pressure. Test results are reported as pass (no penetration) or fail (penetration detected). Unlike degradation testing, penetration testing provides an assessment of protective clothing material barrier performance. Since penetration resistance testing examines only observable amounts of liquid penetration, permeation may still occur. The use of penetration resistance data must be restricted to liquid chemicals, and should be limited to scenarios where there is no reasonable vapor exposure hazard under the conditions of exposure.

INTERPRETATION OF PERMEATION DATA

Permeation is the process of chemical movement through a material on a molecular level. Permeation resistance refers to the ability of a material to retard or prevent chemical movement through it. Permeation may occur without any visible signs of degradation.
Permeation resistance is measured using a test cell which is divided into two halves by a protective clothing specimen. Chemical is placed on the challenge side, while the collection side is periodically monitored for permeating chemical. Permeation data were obtained in accordance with the American Society for Testing and Materials (ASTM) Standard Test Method F 739 (Resistance of Materials Used in Protective Clothing to Permeation by Liquids and Gases), unless stated otherwise. In the case of chemicals that are classified as warfare agents, the data were obtained in accordance with the Military Standard 282 (MIL-STD-282) (Military Standard, Filter Units, Protective Clothing, Gas-Mask Components, and Related Products: Performance Test Methods).
Permeation rate is the amount of chemical that passes through a material for a measured surface area per unit time. In this section, permeation rate is expressed in micrograms per square centimeter per minute (mcg/cm(2)/min). The reported permeation rate is either the steady-state rate or the maximum rate observed during testing. In some cases, very large permeation rates exceed measurement techniques and are reported as ">" (greater than) or "HIGH."
Breakthrough time is the elapsed time, in minutes, from the time the chemical comes in contact with the material exterior surface, to the time that chemical is detected on the interior surface. When no breakthrough is detected, the breakthrough time is report as ">" the testing period. If permeation breakthrough is rapid, results are reported as "<" (less than) the earlier sampling time or as "IMMEDIATELY" (which usually means breakthrough in less than 4 minutes).
The breakthrough time should exceed the expected use period of the selected protective clothing. Additionally, there are several other factors that must be taken into account to provide appropriate protection.
Permeation testing is usually conducted with full strength, undiluted chemical for the duration of the test period. Actual exposures may involve diluted chemical for short or intermittent exposure periods.
Permeation testing is usually conducted at room temperature. Permeation occurs faster at elevated temperatures (short breakthrough times and higher permeation rates) and slower at reduced temperatures (long breakthrough times and lower permeation rates).
Permeation resistance of mixtures cannot usually be determined on the basis of the individual chemicals making up the mixture. Synergistic effects may occur and result in more rapid permeation than accounted for by the individual mixture chemicals.
Permeation rates may be used to calculate potential wearer exposure; however, several assumptions must be made about the extent of exposure and condition of clothing wear. Furthermore, there are few chemicals with dermal exposure limits, making it difficult to determine an acceptable skin exposure level.

ENGINEERING CONTROLS

"Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants." (HSDB , 1998)

-PHYSICAL HAZARDS

FIRE HAZARD

SUMMARY

POTENTIAL FIRE OR EXPLOSION HAZARDS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 129 (ERG, 2004)
- HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
- Vapors may form explosive mixtures with air.
- Vapors may travel to source of ignition and flash back.
- Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks).
- Vapor explosion hazard indoors, outdoors or in sewers.
- Those substances designated with a "P" may polymerize explosively when heated or involved in a fire.
- Runoff to sewer may create fire or explosion hazard.
- Containers may explode when heated.
- Many liquids are lighter than water.
Ethyl formate is a highly flammable liquid; it is considered a very dangerous fire and explosion hazard when exposed to open flame, heat, or oxidizers (ACGIH, 1991; Lewis, 1996).
Toxic vapors and gases, including carbon monoxide, may be released in a fire involving this compound (HSDB , 1998).
This compound is lighter than water: It floats on and mixes with water (AAR, 1996; (CHRIS , 1998).
Its vapors are heavier than air; flashback along a vapor trail is a possibility (AAR, 1996; (CHRIS , 1998).

FLAMMABILITY CLASSIFICATION

NFPA Flammability Rating for CAS109-94-4 (NFPA, 2002):

Listed as: Ethyl Formate
Flammability Rating: 3

(3) Flammable. Liquids and solids that can be ignited under almost all ambient temperature conditions. Including liquids with a flash point below 73 degrees F and a boiling point above 100 degrees F, solid materials which form coarse dusts that burn rapidly without becoming explosive, materials which burn rapidly by reason of self-contained oxygen (ie, organic peroxides), and materials which ignite spontaneously when exposed to air.

Listed as: o-Ethyl Formate
Flammability Rating: 3

(3) Flammable. Liquids and solids that can be ignited under almost all ambient temperature conditions. Including liquids with a flash point below 73 degrees F and a boiling point above 100 degrees F, solid materials which form coarse dusts that burn rapidly without becoming explosive, materials which burn rapidly by reason of self-contained oxygen (ie, organic peroxides), and materials which ignite spontaneously when exposed to air.

FIRE CONTROL/EXTINGUISHING AGENTS

FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 129 (ERG, 2004)

CAUTION: All these products have a very low flash point: Use of water spray when fighting fire may be inefficient.

SMALL FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 129 (ERG, 2004)

Dry chemical, CO2, water spray or alcohol-resistant foam.
Do not use dry chemical extinguishers to control fires involving nitromethane or nitroethane.

LARGE FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 129 (ERG, 2004)

Water spray, fog or alcohol-resistant foam.
Do not use straight streams.
Move containers from fire area if you can do it without risk.

TANK OR CAR/TRAILER LOAD FIRE PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 129 (ERG, 2004)

Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
Cool containers with flooding quantities of water until well after fire is out.
Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
ALWAYS stay away from tanks engulfed in fire.
For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn.

NFPA Extinguishing Methods for CAS109-94-4 (NFPA, 2002):

Listed as: Ethyl Formate
Extinguishing Method(s): 1, 5

1: "Water may be ineffective" applies to a situation where materials with a flash point below 100 degrees F (37.8 degrees C) are burning. Water will only be effective if used by experienced fire fighters under favorable conditions. Even though water may not put the fire out, it can be used to protect equipment and structures.
5: Flammable liquid fires can be extinguished using carbon dioxide, dry chemical, foam, and vaporizing liquid extinguishers, as long as the fires are small to moderate in size and the flammable liquid reservoir is shallow. Use of foam to form a blanket over a flammable liquid is not effective when the liquid is water-soluble. Certain alcohol resistant foams are effective extinguishing agents for polar, non-polar, and water-soluble liquid fires. These foams are preferred for fighting flammable liquid fires except those that involve water reactive flammable liquids.

Listed as: o-Ethyl Formate
Extinguishing Method(s): Not Listed

To combat a fire involving ethyl formate, use alcohol foam, carbon dioxide, or dry chemical. Do not use water directly on this compound. Although, water may be utilized in flooding quantities to cool affected containers/structures. Water should be applied from as great a distance as possible. Do not attempt to extinguish a fire unless the leak can be stopped (AAR, 1996; (CHRIS , 1998; Lewis, 1996).

Utilize dry powder, foam, carbon dioxide, or Halon to extinguish a fire involving this compound (Sittig, 1991).

EXPLOSION HAZARD

Containers of ethyl formate may explode during a fire (CHRIS , 1998).

If ignited within an enclosed area, the vapor may explode (CHRIS , 1998).

DUST/VAPOR HAZARD

Acrid smoke and irritating fumes are produced when ethyl formate is heated to decomposition (Lewis, 1996).

REACTIVITY HAZARD

This compound is incompatible with strong acids, strong alkalis, strong oxidizers, and nitrates (Sittig, 1991).

Upon exposure to moisture, ethyl formate will hydrolyze to formic acid and ethanol (ACGIH, 1991; Budavari, 1996; Lewis, 1996).

From Urben (1995) about Methyl Formate: "The crude product of reaction of methanol and carbon monoxide at 100 degrees C/70 bar in presence of 0.5% of sodium methoxide was discharged after cooling into a storage bottle, which burst 4 hours later. This was attributed to extreme instability of the ester in the presence of the base, leading to the reverse reaction with vigorous evolution of carbon monoxide. Immediate neutralization of the reaction mixture would prevent the decomposition, which also occurs with ETHYL FORMATE and base."

CONTAINMENT/WASTE TREATMENT OPTIONS

SUMMARY

SPILL OR LEAK PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 129 (ERG, 2004)
- ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area).
- All equipment used when handling the product must be grounded.
- Do not touch or walk through spilled material.
- Stop leak if you can do it without risk.
- Prevent entry into waterways, sewers, basements or confined areas.
- A vapor suppressing foam may be used to reduce vapors.
- Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers.
- Use clean non-sparking tools to collect absorbed material.
RECOMMENDED PROTECTIVE CLOTHING - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 129 (ERG, 2004)
- Wear positive pressure self-contained breathing apparatus (SCBA).
- Structural firefighters' protective clothing will only provide limited protection.
Stay upwind to avoid contact with vapors. Remove any possible ignition sources from the area. Water spray may be employed to knock-down vapors, however, do not use the water directly on ethyl formate. Ventilate the area of the spill. Due to the potential explosion hazard, do not allow this compound to enter a confined space (eg, a sewer) (AAR, 1996; (CHRIS , 1998; HSDB , 1998; OHM/TADS , 1998).
Spilled ethyl formate should be absorbed in sand, vermiculite, or other inert absorbent material. Small quantities can be absorbed on paper towels (HSDB , 1998; Sittig, 1991).
For in situ amelioration (in water): A rapid response allows skimming of the ethyl formate slick. Peat or carbon can be employed on the soluble portion. As ethyl formate degrades in water, the formic acid which is formed can be dealt with via anion exchangers (OHM/TADS , 1998).
"At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices." (HSDB , 1998)

WASTE TREATMENT OPTIONS

PHYSICAL TREATMENT

Small quantities of ethyl formate absorbed on paper towels should be allowed to evaporate within a fume hood. When doing this it is important to give enough time so that all vapors can clear the hood ductwork. The paper towels can then be burned in a suitable location (HSDB , 1998).
Larger quantities can be mixed with a flammable solvent, and then sprayed/atomized into an appropriate furnace or incinerator (OHM/TADS , 1998; Sittig, 1991).
Waste management activities associated with material disposition are unique to individual situations. Proper waste characterization and decisions regarding waste management should be coordinated with the appropriate local, state, or federal authorities to ensure compliance with all applicable rules and regulations.

-ENVIRONMENTAL HAZARD MANAGEMENT

POLLUTION HAZARD

Ethyl formate will enter the environment from its manufacture, transport, use, and disposal. It occurs naturally in fruit as well as other products (eg, honey, beer, wine, mussels) (Howard, 1990; HSDB , 1998).

ENVIRONMENTAL FATE AND KINETICS

In the vapor phase it will react with photochemically-produced hydroxyl radicals; this process has an estimated half-life of 11.1 days. As ethyl formate is fairly water soluble, it is expected that rain would wash out some proportion of this compound (Howard, 1990; HSDB , 1998).

WATER

SURFACE WATER
- In water, volatilization will be important; a half-life of 4.5 hours was predicted from a model river. Hydrolysis is also a significant route, especially in alkaline waters: Half-lives of 3.1 days at pH 7 and 7.5 hours at pH 8 have been noted. Biodegradation is also likely. Ethyl formate is not expected to bioconcentrate nor adsorb to sediment (Howard, 1990).

SOIL

TERRESTRIAL
- Volatilization from surface soil is an important route. Ethyl formate will likely leach as it is estimated to be highly mobile in soil. Other significant processes are thought to include hydrolysis and biodegradation (especially in alkaline soil), although there is no specific data to support this (Howard, 1990).

BIODEGRADATION

There are no available data on potential biodegradation of this compound in natural media. The theoretical Biological Oxygen Demand (BOD) was 33% after 10 days with a dispersed seed aeration laboratory screening test using a settled sewage culture (Howard, 1990).

Based on limited data and the fate of similar compounds, ethyl formate is expected to undergo moderate to rapid biodegradation (HSDB , 1998; OHM/TADS , 1998).

BIOACCUMULATION

BIOCONCENTRATION FACTOR

With an estimated BCF of 0.88, ethyl formate is not expected to bioconcentrate in aquatic organisms (Howard, 1990).
This compound did not bioconcentrate in rainbow trout (Howard, 1990).
