Section VII: Special Protection
Use non-sparking tools.
Ventilation: Mechanical exhaust required.
Respiratory Protection: use respirators and components tested and approved under
appropriate government standards such as NIOSH. Where risk assessment shows air-
purifying respirators are appropriate use a full-face respirator with multi-purpose
combination respirator cartridges as a backup to engineering controls. If the respirator is
the sole means of protection, use a full-faced supplied air respirator.
Skin Protection: Compatible chemical-resistant gloves.
Eye Protection: Chemical safety goggles.
Emergency eye wash fountains and safety showers should be available in the vicinity of
any potential exposure.
Section VIII: Spill and Disposal Procedures
Evacuate area. Shut off all sources of ignition. Use non-sparking tools. Wear self-
contained breathing apparatus, rubber boots, and heavy rubber gloves. Ventilate area and
wash spill site after material pickup is complete. Cover with dry-lime, sand, or soda ash.
Place in covered containers using non-sparking tools and transport outdoors.
Waste Disposal: Contact a licensed professional waste disposal service to dispose of this
material. Burn in a chemical incinerator equipped with an afterburner and scrubber but
exert extra care in igniting as this material is highly flammable. Observe all federal, state,
and local environmental regulations.
Section IX: Storage
Toluene container should be tightly closed. Keep away from heat, sparks, and open flame.
This chemical is subject to the notification requirements of section 313 of the Emergency
Planning and Community Right-to-Know Act of 1986. This law requires certain
manufacturers to report on annual emissions of specified toxic chemical and chemical
categories.
