DuPont™ Vertrel® specialty fluid products are generally safe, but as with any chemical it is important for all users to be well educated regarding the product properties, safe handling, and use. Please refer to the information regarding flammability/decomposition, human health, and storage & handling.
Most DuPont™ Vertrel® products do not exhibit a closed-cup flash point, and are not classified as flammable liquids by the National Fire Protection Association (NFPA) or the Department of Transportation (DOT). However, there are some blends that have vapor flammability limits in air. Specific flammability information is provided for each product on the specific product's page.
In the event of a spill or a leak, the vapors above the liquid may fall within the lower explosive limit/upper explosive limit (LEL/UEL) and, therefore, become flammable. Precautions to be taken in this situation are to evacuate the area, provide maximum ventilation, and ensure there are no ignition sources present.
DuPont™ Vertrel® specialty fluids have low inhalation toxicity and pose little risk of adverse health effects when airborne exposures are maintained below established exposure limits. For information on the exposure limits for each DuPont™ Vertrel® product, because they vary, refer to the specific product's brochure.
DuPont™ Vertrel® vapors are transparent, with only a slight odor. The vapors are four to eight times heavier than air and can, therefore, collect and concentrate near the floor or in low-lying areas. High vapor concentration can result in suffocation due to oxygen deficiency. It is unsafe to enter a tank, vapor degreaser, or other confined space without observing safe entry procedures.
Storage & Handling
DuPont™ Vertrel® specialty fluids are often shipped in drums of up to a 55-gallon capacity, which can weigh in excess of 600 pounds. Full drums are best moved by forklift trucks onto racks to provide gravity feed to the point of use. Whenever drums are handled to transfer cleaning agents, to empty drums, or to be moved manually, several precautions should be observed.
Wear proper safety gear including gloves, splash goggles, and safety shoes when drums are to be moved and aprons when handling open drums.
Before the drums are moved, make sure the bungs are tightly closed to prevent splashing.
When working near other drums and equipment, be careful of pinch points.
Any drum containing solvent should be kept tightly sealed between transfer operations to prevent unnecessary evaporation loss. Drums should be stored with the bung tightly closed to eliminate the possibility of incurring a major spillage of solvent through loose or leaky bungs.
When dispensing DuPont™ Vertrel® specialty fluids, avoid splashes, spills, and leaks. In the event of a spill, provide plenty of ventilation to circulate the air at the spill level. If the spill is large, evacuate the area until the concentration of vapors is reduced to safe levels.
