Material safety data sheet
Methanol
Plug the leak, cut off the supply
Dam up the liquid spill
Try to reduce evaporation
Recover methanol or dilute with water to reduce fire hazard
6.3 Clean-up:
Eliminate all ignition sources
Fluorocarbon alcohol resistant foams may be applied to spill to diminish vapour and fire hazard
Maximize methanol recovery for recycling or reuse
Collect liquid with explosion proof pumps
For small spills: take up into non-combustible sorbent
7. Handling and storage
7.1 Handling:
Reduce/avoid exposure and/or contact
Keep container tightly closed
No smoking or open flame
Use spark-/explosionproof appliances and lighting system
Take precautions against electrostatic charges
Handle uncleaned empty containers as full ones
7.2 Storage:
Keep away from heat and ignition sources, oxidizers, acids, bases
Store in a dry and well-ventilated area
Store in totally enclose equipment
Tanks must be grounded and vented and should have vapour emission controls
Provide for a tub to collect spills
Issue date : May 2001 3 / 7
7.3 Materials for packaging:
Anhydrous methanol is non-corrosive to most metals at ambient temperatures except lead and
magnesium
Coatings of copper (or copper alloys), zinc (including galvanized steel) or aluminium are unsuitable for
storage as they are attacked slowly
Mild steel is the recommended construction material for tanks
8. Exposure controls/Personal protection
8.1 Recommended engineering controls:
In confined areas, local and general ventilation should be provided to maintain airborne concentrations below
permissible exposure limits
Ventilation systems must be designed according to approved engineering standards
Sampling methods:
NIOSH 2000
