First aid

General first aid measures. Get medical advice if you feel unwell

If inhaled
IMMEDIATELY leave the contaminated area, take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used, if not available, use a level of protection greater than or equal to that advised under Protective Clothing.
Skin contact
CAUTION: Exposure of skin to compressed gases may result in freezing of the skin. Treatment for frostbite may be necessary. Remove the victim from the source of contamination. IMMEDIATELY wash affected areas gently with COLD water (and soap, if necessary) while removing and isolating all contaminated clothing. Dry carefully with clean, soft towels. Call a hospital or poison control center IMMEDIATELY even if no symptoms (such as inflammation or irritation) develop. Be prepared to transport the victim to a hospital for treatment after washing the affected area if advised to do so by a physician.
Eye contact
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
If swallowed
This compound is a gas, therefore inhalation is the first route of exposure. OTHER: Since this chemical is a known or suspected carcinogen you should contact a physician for advice regarding the possible long term health effects and potential recommendation for medical monitoring. Recommendations from the physician will depend upon the specific compound, its chemical, physical and toxicity properties, the exposure level, length of exposure, and the route of exposure.

Handling, storage and disposal

Summaries only, follow the supplier SDS for your grade

Safe handling

Fire: NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding) if in liquid state. Use non-sparking handtools.

General: STRICT HYGIENE!

Inhalation: Use ventilation, local exhaust or breathing protection.

Skin: Cold-insulating gloves. Protective clothing.

Eyes: Wear face shield or eye protection in combination with breathing protection.

Ingestion: Do not eat, drink, or smoke during work.

Storage

Fireproof.

Disposal

Ethyl chloride is a waste chemical stream constituent which may be subjected to ultimate disposal by controlled incineration. Incineration of ethyl chloride, preferably after mixing with another combustible fuel. Care must be exercised to assure complete combustion to prevent the formation of phosgene. An acid scrubber is necessary to remove the halo acids produced. Ethyl chloride boils @ 12 °C, therefore it is commonly a gas at ambient temp, and will be in pressurized cylinders. Thermal destruction methods may be difficult to apply unless a gas feed to the incinerator can be arranged. (Peer-review conclusions of an IRPTC expert consultation (May 1985))

Exposure limits and toxicity

Occupational exposure limits and toxicity data

OSHA PEL, 8-hour TWA
1000 ppm (2600 mg/m³)
ACGIH TLV, 8-hour TWA
100 ppm
IDLH
3800 ppm (10% LEL)

Short-term exposure: The substance is mildly irritating to the eyes, skin and respiratory tract. Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system. Exposure far above the OEL could cause unconsciousness, cardiac dysrhythmia and death.
