10.4
Formation of peroxide compounds pose a number of safety hazards, with
the potential for very serious injury and damage to property. These safety
hazards include:
10.4.1
Explosive decomposition reactions and
10.4.2
Violent, possibly explosive, auto-polymerization of certain unsaturated
compounds, initiated by formation of peroxides.
10.5
Labeling of Incoming Material Requirements
10.5.1
On arrival to the laboratory, the labels on containers of materials
susceptible to peroxide formation must be:
10.5.1.1
Inspected to determine whether they include the warning “Peroxide
Former” or “Peroxidizable”. This information must be added, if not already
present.
10.5.1.2
Labeled with the date (MM/DD/YY) on which the material was received
and the identity of a responsible employee, group or department.
10.6
Storage Requirements
10.6.1
Peroxidizable materials must be stored in compliance with supplier SDS
recommendations.
10.6.2
If possible, the original suppliers container should be used. Otherwise, use
containers that strictly conform to manufacturers recommendations.
10.6.3
Containers should be kept tightly sealed to prevent both ingress of
additional atmospheric oxygen and also to prevent evaporation of volatile
compounds.
10.7
Handling and Use Requirements Before using a container of peroxidizable
material:
10.7.1
Ensure that the material is within its approved storage / disposal limits
(see schedule below).
10.7.2
Examine the condition of the container. If a viscous condensate, crystals
or other solids are discovered in any peroxidizable material container
(even one that is otherwise empty), DO NOT TOUCH OR MOVE THE
CONTAINER. Post a warning sign, keep others away and immediately
contact the ERT (#78600).
10.7.3
Once a container is opened, the container should be dated
(DD/MM/YYYY) and the chemical should be tested for peroxides not less
frequently than once every month and dispose of after six months.
