2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
POISON. Swallowing will cause burns to the mouth and throat, gastrointestinal irritation, and may be fatal. Health affect may be parallel those from inhalation. Eye
Vapours cause severe eye irritation with swelling, burning, redness and discharge. Liquid contact can produce penetrating burns and possible permanent coneal opacity with visual impairment. Temporary blindness may occur with a severe exposure. Skin
Causes severe skin irritation and burns. Is a skin sensitiser. Absorption may occur with effects similar to inhalation overexposure. Inhaled
Vapours will irritate or burn the mucous membranes and upper respiratory tract. 2.2 Health Effects - Chronic
Overexposure can produce severe health effects, including narcosis, pulmonary oedema, weight loss, weakness, tremors, burning sensation, dizziness, nausea, convulsions and sensitisation. Hydrazine concentration considered to be immediately dangerous to life and health is 80 ppm.
2.3 First Aid
Swallowed
If swallowed, DO NOT induce vomiting. Give large quantities of water. Never give anything by mouth to an unconscious person. Get medical attention immediately.
Eye
Immediately flush eyes with plenty of water for at least 15 minuutes, lifting lower and upper eyelids occassionally. Get medical attention immediately.
Skin
Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clohting and shoes. Get medical attention immediately. Wash clothing before reuse. Thoroughly clean shoes before reuse.
Inhaled
Remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately.
First Aid Facilities
Ensure an eye bath and safety shower is readily available.
2.5 Advice to Doctor
Treat symptomatically and supportively.
2.6 Toxicity Data
Oral LD50 = 129 mg/kg (rat). Investigated as a tumorigen, mutagen and reproductive effector.
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
For Hydrazine (CAS 302-01-2) - OSHA (PEL) = 1 ppm (TWA), skin. ACGIH (TLV) = 0.01 ppm (TWA), skin, A3 - animal carcinogen. NIOSH (REL) = 0.03 ppm (2 hr), ceiling, potential occupational carcinogen.
3.2 Engineering Controls
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits.
3.3 Personal Protection
Respiratory protection - if the exposure limit is exceeded, wear a supplied air, full-facepiece respirator, airlined hood, or full-facepiece self-contained breathing apparatus. Eye protcetion - wear chemical safety goggles and/or full face shield where splashing is possible. Skin protection - wear impervious protective clothing including boots, gloves, lab coat, apron or overalls as appropriate to prevent skin contact.
3.4 Flammability
Product is combustible. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Keep in a tightly closed container. Store in a cool, dry, ventilated area away from sources of heat or ignition. Avoid contact with incompatible materials such as powerful reducing; reacts vigorously with most oxidising materials. Incompatible with acids, wood and cloth. Contact of vapour with metal oxides such as iron, copper, lead and molybdenum can result in fire and possible explosion.
4.2 Packaging / Labelling UN No. 2030 Class 8 Sub Risk 61 Hazchem Code 2P Pack Group II EPG No. 19D Shipping Name HYDRAZINE AQUEOUS SOLUTIONS with less than 64% Hydrazine Hazard TOXIC
Risk Phrases R24/25 Toxic in contact with skin and if swallowed. R34 Causes burns. R40:HYHYDR Possible risk of irreversible effects.
Safety Phrases S36/37/39 Wear suitable protective clothing, gloves and eye/face protection.
4.3 Spills and Disposal
Spills
Wear full protective gear when handling this product. Avoid all ignition sources.
Evacuate danger area. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to a safe place. DO NOT absorb in saw-dust or other combustible absorbents. DO NOT let this chemical enter the environment.
Disposal
Whatever cannot be saved for recovery or recycling should be handled as hazardous waste and sent to a RCRA approved waste facility. Processing, use or contamination of this product may change the waste management options. Dispose of container and unused contents in accordance with federal, state and local requirements.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Combustible liquid and vapour. Hydrazine vapour in air is flammable at and above 4.7% (hydrazine by volume); handle under nitrogen. Above flash point explosive vapour-air mixtures may be formed.
Extinguishing Media
Use waterspray, dry chemical,alcohol foam or carbon dioxide. In the event of a fire, wear full protective clothing and NIOSH approved self-contained breathing apparatus with full facepiece oeprated in the pressure demand or other positive pressure mode. 5 OTHER INFORMATION
Other Information
