BLUE DEF® 4
Protective Equipment For Fire Fighters: For fires beyond the incipient stage, emergency responders in the
immediate hazard area should wear bunker gear. When the potential chemical hazard is unknown, in enclosed or
confined spaces, or when explicitly required by DOT, a self-contained breathing apparatus should be worn. In
addition, wear other appropriate protective equipment as conditions warrant. (See Section 8.)
6. ACCIDENTAL RELEASE MEASURES
Protect People: Wear appropriate protective equipment, including respiratory protection, as conditions warrant.
(See Section 8.)
Protect the Environment: To prevent spilled material from entering sewers, storm drains or natural watercourses,
contain material with a dike or with appropriate absorbent materials such as sand, clay, soil or commercially
available absorbent. Place reclaimed liquid and absorbent into recovery or salvage drums for disposal. Refer to
Section 13 for appropriate disposal.
Cleanup: Stop the source of the release if it can be done without risk. Immediately isolate the hazard area and
restrict access to authorized personnel only.
7. HANDLING AND STORAGE
Handling: Do not enter confined spaces such as tanks or pits without following proper entry procedures such as
ASTM D-4276 and 29CFR 1910.146. The use of appropriate respiratory protection is advised when concentrations
exceed any established exposure limits. (See Sections 2 and 8.) Wash thoroughly after handling. Do not wear
contaminated clothing or shoes. Use good personal hygiene practice.
Storage: Keep container(s) tightly closed. Do not heat or contact with strong oxidizers. Use and store this material
in cool, dry, well-ventilated areas. Do not store at temperatures below 40º F. Store only in approved containers.
Keep away from any incompatible material. (See Section 10.) Protect container(s) against physical damage.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Respiratory Protection: Respiratory protection is not usually required. If significant spray or mist occurs, wear a
NIOSH approved or equivalent dust respirator.
Skin Protection: The use of gloves impermeable to the specific material handled is advised to prevent skin contact,
possible irritation and absorption. (See glove manufacturer for information on permeability.)
Eye Protection: Approved eye protection to safeguard against potential eye contact, irritation or injury is
recommended. Depending on conditions of use, a face shield may be necessary.
Engineering Controls: If current ventilation practices are not adequate to minimize exposure, additional
ventilation or exhaust systems may be required.
Other Protective Equipment: A source of clean water should be available in the work area for flushing eyes and
skin. Impervious clothing should be worn as needed.
