3. Hazards Identification
Emergency Overview
DANGER! Flammable liquid and gas under high pressure. Keep away from heat, sparks, flames and similar ignition
sources. Will form explosive mixtures with air. Faintly disagreeable odour due to ethyl mercaptan odourizer. General
asphyxiate and may cause dizziness, drowsiness vomiting and loss of consciousness. Self contained breathing
apparatus may be required by rescue workers.
Effect of an Acute Overexposure
Eye Contact: No harm expected from vapour, liquid may cause frostbite or other tissue damage
Skin Contact: No harm expected from vapour, liquid may cause frostbite
Ingestion: Not a common route of exposure, liquid contact with lips may cause frostbite
Inhalation: General asphyxiant with effects due to lack of oxygen. May cause headaches, dizziness,
drowsiness, dizziness, nausea, vomiting and unconsciousness.
Effect of Chronic Overexposure
Eye Contact: None expected
Skin Contact: None expected
Ingestion: None expected
Inhalation: Death due to suffocation, ethyl mercaptan is toxic and may pose risk

Protection of Firefighters
DANGER! Evacuate all personnel from area. Will form explosive mixtures with air. Cool cylinders from an extended
distance with a water spray but DO NOT extinguish flames. Remove sources of ignition. Lingering explosive
atmospheres may remain. Containers are equipped with pressure relief device to vent contents in emergency
situation. If pressure relief system fails, cylinders may explode.
6. Accidental Release Measures
Personal Precautions
DANGER! Evacuate all personnel from area. Will form explosive mixtures with air. Remove sources of ignition.
Lingering explosive atmospheres may be created and travel with air currents. Use a self contained breathing
apparatus if substance release is significant. Shut off leak if possible without risk. Actively ventilate area and check
atmosphere with appropriate device before re-entering.
Environmental Precautions and Containment/Cleaning Methods
None
7. Handling and Storage
Handling Precautions
Properly train all employees on proper handling procedures. Handle cylinders with care and avoid jolting, dropping
and impact. Always wear metatarsal shoes when handling and moving cylinders. Use an appropriate hand truck to
move cylinders. Ensure valve protection cap is on whenever gas is not being drawn. Keep cylinders upright and
secured to a wall or immovable object during use. Avoid damaging cylinder labels.

Gas (Propane)
Storage Precautions
Store in a secured, well ventilated and cool area below a temperature of 52癈. Store away from sunlight, fire exits,
sparks, heat and high traffic areas. Firmly secure cylinders upright with the valve protection cap in place by hand.
Store empty and full cylinders separately. Use a first in/first out inventory system to avoid storing cylinders for an
extended period of time
Separate cylinders from oxidizing agents such as oxygen and chlorine. They must be separated by at least 6m or by a
barricade at least 1.5m tall with a fire rating of at least 30 minutes. Post `No Smoking' signs around storage area and
ensure there are no other sources of ignition such as welding arcs or old wiring. Never place a cylinder where it could
become part of an electrical circuit.
8. Exposure Controls and Personal Protection
Exposure Limits
Component CAS # TLV-TWA TLV-STEL IDLH
Propane 74-98-6 - - -
Ethyl Mercaptan 75-08-1 .5ppm 0 500
Ethyl mercaptan is generally not considered hazardous at the concentrations present in propane. However, take
reasonable action to avoid inhalation.
Environmental Controls
Explosion proof general exhaust system.
Personal Protective Equipment (PPE)
Eye / Face: Wear safety glasses or goggles when drawing gas. Always wear goggles/welding helmet with a
filter screen when welding, cutting or brazing.
Skin: Wear work gloves when handling cylinders. Cover exposed skin with flame retardant material.
Respiratory: Wear an approved respirator when welding, cutting or brazing to remove hazardous fume and
gas byproducts.
General Hygiene: Wash hands before and after shift to remove potentially harmful toxic residues.
Other: Always wear metatarsal shoes while handling cylinders and operating within a manufacturing
environment.
