Fire fighting procedures: Cool fire exposed containers with water spray. Remove containers from the fire area if possible. Do not release runoff
from fire control methods to sewers or waterways.
Fire fighting equipment: Firefighters should wear positive pressure self-contained breathing apparatus (SCBA) and consider use of unmanned
hose holders or monitor nozzles for fighting large fires.
6. Accidental release measures
Small spill: Evacuate unnecessary personnel from the spill area. Wear necessary personal protective equipment (PPE) as specified in the SDS or
the site emergency response plan. Eliminate all sources of ignition. Ensure adequate ventilation. Dike and contain spill. Prevent product from

TC-812 REV 1 PART A
Water spill: Do not discharge into drains, surface waters, or groundwater.
General procedures: Refer to section 8 of SDS for personal protection details.
Release notes: Composition and extent of any spill should be evaluated against local regulations and reported to the proper agencies, if necessary.
7. Handling and storage
General procedures: Avoid contact with eyes, skin and clothing. Use only with adequate ventilation. Avoid breathing vapor over open containers.
Avoid open container exposure to damp air. Avoid breathing aerosols, mists, and vapors.
Precautions for safe handling: Avoid contact with eyes, skin, and clothing. Use only with adequate ventilation. Do not breathe vapors, mists, or
dust. Use appropriate personal protective equipment (PPE) as specified in Section 8. Use in a well-ventilated area. Handle and use in a manner
consistent with good industrial/manufacturing techniques and practices.
Conditions for safe storage: Store in a cool, dry place, away from excessive heat, in original or similar container. Avoid unnecessary contact.
Protect from freezing. Containers should be tightly sealed to prevent contamination with foreign materials. Do not reseal container if moisture or
water contamination is suspected. Water contaminated material in a sealed container may rupture due to pressure buildup.

Appropriate engineering controls: Use process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels
below recommended exposure limits.
Individual protection measures, such as personal protective equipment
Eye / face protection: Safety goggles or glasses are recommended. Plastic face shields should be used for complete face protection to protect
against possible splashing or spraying of material. ANSI Z87.1 or approved equivalent.
Skin protection – hand protection: Chemical-resistant gloves and chemical goggles, face-shield, and synthetic apron or coveralls should be
used to prevent contact with eyes, skin, or clothing. Wear nitrile or neoprene gloves. Chemical resistant gloves lined with polyethylene offer
maximum protection.
Respiratory protection: Exhaust ventilation recommended. An organic vapor cartridge or fresh air supplied respirator (NIOSH approved) may
be necessary for certain applications. Consider the type of application, environmental concentrations, and other materials being used
concurrently when determining respirator use and selection. Observe OSHA regulations for respirator use (29 CFR 1910.134).
Skin protection – other: Protective clothing should be selected and used in accordance with “Guidelines for the Selection of Chemical
Protective Clothing” published by ACGIH.
Occupational hygiene practices: Contaminated clothing should be changed and washed before reuse. Eating, drinking and smoking in immediate
work area should be prohibited. Wash hands before eating.
Other use precautions: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Training is
important. Follow all label precautions.
