HYDROGEN PEROXIDE
Use
Handling of hydrogen peroxide (30%- 50%) solutions.
Hazards
Class 5 – Oxidizing Agent. Extremely hazardous substance. Oxidizer /
corrosive. Not flammable but may start fire in contact with organic
materials. Avoid skin contact, serious burns may result.
Risk Control Measures
Only use Hydrogen peroxide after receiving safety training
(Laboratory Induction & Authorisation). Gloves made of nitrile,
neoprene, PVC and natural rubber can provide effective skin protection.
Wear safety glasses or chemical safety goggles with face shield when
using large quantities or chemical safety goggles when using small
quantities. Wear rubber, neoprene or PVC apron when using large
quantities and splash potential exists.
Engineering / Ventilation Controls
Fume hoods should be used when using large quantities and when
potential for reaction releasing hazardous products exists. An eyewash
facility must be available and accessible to areas where hydrogen
peroxide is used.
Storage Requirements
Hydrogen peroxide is a strong oxidizer. Store in a cool, dark area
away from combustibles, organic materials, heat, strong bases, reducing
agents, powdered metals, metallic salts and alkalis. Minimise quantities
stored and rotate stock. Inspect periodically for bulging containers.
Contamination from any source (dust, metals) may cause rapid
decomposition with generation of large quantities of oxygen and high
pressures. Hydrogen peroxide should not be stored directly on wooden
shelves. Store in secondary containment such as plastic tub.
First Aid / Spill Control Procedures
Wash off immediately with copious amounts of cold water (at least 10
minutes). Contaminated clothing should be removed as soon as possible
and thoroughly washed.
In case of contact with eyes, immediately flush eyes with copious
amounts of water for at least 15 minutes (eyewash).
Seek medical attention. Poisons Information Centre (0 13 1126).
Hydrogen peroxide may release oxygen and accelerate combustion. Hydrogen
peroxide may react with organic materials and cause fire.
Small spills:
Wear protective equipment. Flood area with excess water to dilute
solution. Do not attempt cleanup if you feel unsure of your ability to
do so or if you perceive the risk to be greater than normal laboratory
operations. Use a large quantity of water to wash down spills and reduce
the flammable vapours. Keep hydrogen peroxide out of confined spaces,
such as a sewer, because of the possibility of an explosion. Wear
self-contained breathing apparatus and full protective equipment.
Large Spills:
Notify others in the area of spill. Turn off ignition sources in area.
Evacuate area. Call the Molecular Sciences General Office (9479 2160) or Zisis Pouros (9479
1294) for cleanup. Barricade area with tape to prevent entry until
arrival of response personnel. Provide assistance and information to
spill response team.
Waste
Decontamination: Dilute with water.
Contact the Molecular Sciences General Office (9479 2160) for current waste disposal
instructions.
