First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Remove from exposure immediately. Use a bag valve mask or similar device to perform artificial respiration (rescue breathing) if needed. Get medical attention.

Skin contact

Remove contaminated clothing, jewelry, and shoes immediately. Wash with soap or mild detergent and large amounts of water until no evidence of chemical remains (at least 15-20 minutes). Get medical attention, if needed.

Eye contact

Wash eyes immediately with large amounts of water or normal saline, occasionally lifting upper and lower lids, until no evidence of chemical remains. Get medical attention immediately.

Ingestion

Contact local poison control center or physician immediately. Never make an unconscious person, vomit or drink fluids. When vomiting occurs, keep head lower than hips to help prevent aspiration. If person is unconscious, turn head to side. Get medical attention immediately.

Immediate Medical Attention

Get medical attention immediately.

Medical Treatment

For ingestion, consider gastric lavage and activated charcoal slurry.

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

alcohol resistant foam, carbon dioxide, regular dry chemical, water, alcohol resistant foam. Large fires: Use alcohol-resistant foam or flood with fine water spray.

Unsuitable media

Water may be ineffective.

Specific hazards

Severe fire hazard. The vapor is heavier than air. Vapors or gases may ignite at distant ignition sources and flash back. Vapor/air mixtures are explosive above flash point.

Instructions

Move container from fire area if it can be done without risk. Cool containers with water spray until well after the fire is out. Stay away from the ends of tanks. For fires in cargo or storage area: Cool containers with water from unmanned hose holder or monitor nozzles until well after fire is out. If this is impossible then take the following precautions: Keep unnecessary people away, isolate hazard area and deny entry. Let the fire burn. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tanks due to fire.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Stop leak if possible without personal risk. Keep unnecessary people away, isolate hazard area and deny entry. Stay upwind and keep out of low areas.

Small spill

Absorb with sand or other non-combustible material. Collect spilled material in appropriate container for disposal.

Large spill

Dike for later disposal.

Cleanup methods

Absorb with sand or other non-combustible material. Collect spilled material in appropriate container for disposal.

Materials: sand or other non-combustible material, absorbent sheets, spill-control pads or pillows

07

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Store and handle in accordance with all current regulations and standards. Grounding and bonding required. Keep separated from incompatible substances.

Storage

Subject to storage regulations: U.S. OSHA 29 CFR 1910.106.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

Provide local exhaust ventilation system. Ventilation equipment should be explosion-resistant if explosive concentrations of material are present. Ensure compliance with applicable exposure limits.

Hands

Wear appropriate chemical resistant gloves.

Eyes

Wear splash resistant safety goggles.

Respiratory

The following respirators and maximum use concentrations are drawn from NIOSH and/or OSHA. 3000 ppm: Any supplied-air respirator. Any powered, air-purifying respirator with organic vapor cartridge(s). Any chemical cartridge respirator with a full facepiece and organic vapor cartridge(s). Any air-purifying respirator with a full facepiece and an organic vapor canister. Any self-contained breathing apparatus with a full facepiece. Any supplied-air respirator with a full facepiece. Escape - Any air-purifying respirator with a full facepiece and an organic vapor canister. Any appropriate escape-type, self-contained breathing apparatus. For Unknown Concentrations or Immediately Dangerous to Life or Health - Any supplied-air respirator with full facepiece and operated in a pressure-demand or other positive-pressure mode in combination with a separate escape supply. Any self-contained breathing apparatus with a full facepiece.

Skin/Body

Wear appropriate chemical resistant clothing.
