The materials most commonly used in composite manufacture are:
resins, catalysts, and strengthening materials (fiberglass, Kevlar, Scorefoam).
Polyester, vinylester, and epoxy are the most commonly used resins today with
the catalysts being either Methyl Ethyl Ketone Peroxide (MEKP), Benzoil
Peroxide, or an epoxy Part B catalyst (depending on the system used).
Fiberglass, carbon fiber, Kevlar and Scorefoam are the most commonly used
strengthening materials. Depending on the use of the material, they all produce
The hazards commonly experienced with these types of materials
are: overexposure to vapors, inhalation of particulate fiber, industrial
dermatitis (rashes, irritation, and other skin disorders) and the potential for
severe eye injury with catalysts and by flying particles from grinding composite
materials. It is extremely important to use safety glasses, at a minimum, when
using catalysts and when grinding composite material.
The majority of these hazards can be controlled by using the
proper personal protective equipment (PPE) for the chemicals and materials you
are using. The following is a short guide on the use of PPE and when they should
be in use. Consult the MSDS on the particular chemical for the proper PPE you
should wear and have your supervisor explain the use and care of the specific
personal protective equipment needed.

When grinding or sanding any composite material, a quality
respirator rated for the task must be worn. Many composite materials have glass,
carbon, or Kevlar strands that, when ground, will produce an airborne
respiratory contaminate. This dust, when inhaled, can be irritating and
potentially damaging to the respiratory system.
When you recognize the inherent hazards of composite materials, you can better equip yourself for protection. Ask your supervisor if you have any questions regarding the chemicals or materials you work with and the best way to protect yourself while using them.
