DIMETHYLAMINE

Dimethylamine is an eye irritant; it is corrosive to the eyes, skin, and mucous membranes. Both the gas and aqueous solution are toxic and corrosive. Gases or vapors from aqueous solutions may cause irritation, conjunctivitis, and corneal damage. Inhalation may cause coughing, nausea, and pulmonary edema. Contact with the gas or anhydrous liquid may cause frostbite. Dermatitis and conjunctivitis are occasionally observed in chemical workers after prolonged exposure. No systemic effects from industrial exposure have been reported.

The following information is for CORROSIVES-ALKALINE:

Exposure to alkaline corrosives may result in severe burns depending on the type of alkaline corrosive agent, concentration, and duration of exposure.
Rarely, patients may not present until esophageal stricture has occurred and history may reveal caustic ingestion. Acidosis is due to severe tissue burns and shock.

Some substances may be irritating or corrosive depending on concentration, molarity and other factors.

For more information, refer to the "IRRITANTS" MEDITEXT(TM) Medical Management.

Stridor, vomiting, and drooling were associated with serious esophageal injury in 50 to 67% of cases. The presence of second or third degree burns were noted by endoscopic examination in 9 to 22% of cases in the absence of symptoms (stridor, vomiting, drooling, or cheek, lip, or oropharynx lesions).

FIRST AID

GENERAL -

The following information is for Corrosives-Alkaline.
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.
Administer oxygen, determine blood gases and obtain a chest x-ray.
If pulmonary edema is present, consider positive end expiratory pressure ventilation and steroids.

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).

EYE EXPOSURE -

Exposed eyes should be irrigated with copious amounts of water for at least 30 minutes. An examination should always be performed. Ophthalmologic consultation should be obtained.

ORAL EXPOSURE -

The use of diluents is controversial. Residual perioral alkali should be rinsed with milk or water. Activated charcoal is NOT indicated.
Neutralization is contraindicated.
Emesis or gastric lavage should be avoided. Patient should be NPO following dilution until after surgical consultation.
Esophagoscopy should be performed 12 to 24 hours post-ingestion to assess severity where history indicates a definite ingestion of a caustic agent or where stridor, dysphagia or drooling are present.

Esophagoscopy is not indicated for asymptomatic bleach, ammonia (household), and non-phosphate detergents.
The esophagoscope should not be passed beyond the first circumferential burn for fear of perforation. A flexible tube is usually preferred.
Second or third degree burns have been reported in 9 to 22% of asymptomatic patients.

Although controversial, consider with caution administration of pharmacologic doses of steroids (1 mg/kg prednisone) where deep or circumferential esophageal burns are detected on esophagoscopy. Continue therapy for 3 weeks then taper if burns are found or esophagoscopy is not performed.
Antibiotics should be used only for specific indications of infection.
Consider performing a barium swallow at 10 days to 3 weeks following initial burn to assess severity of esophageal damage.
Dilation may be necessary when there is evidence of esophageal strictures. Intervals between dilatations per appropriate surgical consult.
Intraposition of the colon may be necessary if dilatation fails to provide an adequate sized esophagus. Some surgeons prefer a gastric tube to colonic intraposition.

GENERAL/SUMMARY

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

ANIMAL DATA

In a 2-year inhalation study, groups of male and female rats and mice were exposed 6 hours/day, 5 days/week at 10, 50, or 175 ppm of dimethylamine. It appeared from the study that 10 ppm was close to a no-observed-effect level (NOEL) for respiratory irritation (ACGIH, 1991).
Corneal injury, irritation of the respiratory tract, and hepatic injury occurred in guinea pigs and rabbits repeatedly exposed to concentrations of approximately 100 to 200 ppm for 18 to 20 weeks (Hathaway et al, 1991).
Various species of laboratory animals survived 5 ppm of continuous exposure for 90 days without signs of toxicity, but at autopsy some showed mild inflammatory changes in the lungs (Hathaway et al, 1991).
Dimethylamine is irritating and corrosive to both the eyes and skin of test animals. Skin contact with the liquid causes necrosis, and a drop in the eye may result in severe corneal injury or permanent corneal opacity (Hathaway et al, 1991; ACGIH, 1991).

GENERAL INFORMATION

This section provides a compilation of chemical resistance information and test data for specific protective clothing products. Chemical resistance information includes both degradation resistance ratings and permeation resistance data. This information is designed to assist in the selection of appropriate protective clothing. Only data on specific products and manufacturers are included. Generic information or recommendations are not provided since significant differences can exist in the chemical resistance for apparent similar product types.
Specific product information is organized by general product type (gloves, garments, and footwear), material type, and manufacturer. 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.

Generators of waste equal to or greater than 100 kg/month containing dimethylamine, US Environmental Protection Agency hazardous waste number U092, must conform with EPA regulations in storage, transportation, treatment and disposal of such wastes (40 CFR 260-270) (HSDB , 1993).
At the time of this 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 , 1993).
ENVIRONMENTAL CONSIDERATIONS - LAND SPILL (Dimethylamine, Anhydrous) (AAR, 1987)
- Dig a pit, pond, lagoon, or holding area to contain liquid or solid material.
- Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete.
- Absorb bulk liquid with fly ash, cement powder, or commercial sorbents.
- Neutralize with sodium bisulfate.
ENVIRONMENTAL CONSIDERATIONS - WATER SPILL (Dimethylamine, Anhydrous) (AAR, 1987)
- Use natural barriers or oil spill control booms to limit spill travel.
- Use surface active agent (eg, detergent, soaps, alcohols), if approved by EPA.
- Inject "universal" gelling agent to solidify encircled spill and increase effectiveness of booms.
- If dissolved in region of 10 parts per million or greater concentration, apply activated carbon at ten times the spilled amount.
- Add sodium bisulfate.
- Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
ENVIRONMENTAL CONSIDERATIONS - AIR SPILL (Dimethylamine, Anhydrous) (AAR, 1987)
- Apply water spray or mist to knock down vapors.
- Vapor knockdown water is corrosive or toxic and should be diked for containment.
ENVIRONMENTAL CONSIDERATIONS - LAND SPILL (Dimethylamine, Aqueous) (AAR, 1987)

-ENVIRONMENTAL HAZARD MANAGEMENT

POLLUTION HAZARD

Dimethylamine is released to the environment primarily as emissions during its production and use as a chemical intermediate. It also occurs naturally in food and as a metabolic product (HSDB , 1993).

AIR: Dimethylamine, released into the atmosphere, will react with photochemically produced hydroxyl radicals (half-life: 5.9 hours). Dimethylamine will disappear more rapidly under polluted atmospheric conditions when nitrogen oxide concentrations are high. Due to its high water solubility, washout by rain will also be an important removal process (HSDB , 1993).

WATER: If released into water, dimethylamine will volatilize slowly (estimated half-life of 35 hours in a model river). Biodegradation will be rapid (half life: 1.5 days) and is the most important removal process in most natural waters. Direct photolysis and adsorption to sediment will not be significant. However, in water containing nitrite, dimethylnitrosamine is formed photochemically from dimethylamine, especially at higher pH levels. Bioconcentration in aquatic organisms is not expected to be significant (HSDB , 1993).

SOIL: Dimethylamine is a gas at room temperature with a low adsorptivity to soil. If released on soil, it will probably volatilize rapidly and leach readily through the soil. Biodegradation should be the most important degradative process and removal of the chemical should occur in several weeks (HSDB , 1993).
