10.5 Incompatible Materials
Acids
Strong Bases
Oxidizers (e.g. peroxides, perchlorates, nitrates, etc.)
Acid chlorides
Acid anhydrides
Alkali metals
Reducing agents.
May react with rubbers, plastics and coatings
Incompatible Materials refers to substances that must not be mixed or
stored together with the hazardous product, as doing so may result in a
hazardous reaction. These types of reactions may lead to explosions, fires,
the release of toxic gases, or changes to the physical properties of the
chemicals.
10.6 Hazardous Decomposition Products
Carbon oxides
Hydrogen gas
Volatile organic compounds that may be toxic
Hazardous Decomposition Products are chemicals that can be emitted
when the hazardous product breaks down due to instability, combustion
(burning), thermal decomposition (heating) and chemical reactions. In this
example, the hazardous product may emit Carbon Oxides (e.g. Carbon
Monoxide), Hydrogen gas and toxic volatile organic compounds. These
biproducts must be controlled as they may result in suffocation, health
effects, fires and explosions.
SECTION 11: TOXICOLOGICAL INFORMATION
This section provides technical information related to toxicology and
health effects associated with the hazardous product or its ingredients.
The information found in this section can be used to support information
provided in section 2. In general, data may be provided that indicates the
consequences of exposure. This will include signs, symptoms and effects
that the exposure could produce.
11.1 Likely Routes of Exposure
Inhalation
Skin Contact
Eye Contact
This area will showcase the ways the hazardous product can enter a
person's body. The controls present in section 8 should correspond with
these routes of entry. In this example, exposure to the hazardous product
can occur through inhalation (breathing), skin and eye contact.
