Personal Respiratory Protection Information

We have fifty standard colors as shown below.

We can also match any custom color or cross reference to another manufacturer.

The necessary respiratory protection depends upon many factors including duration/level of exposure and conditions of use. In general, exposure to the organic chemicals contained in this product may not require the use of respiratory protection if used in well ventilated areas. In restricted ventilated areas a NIOSH approved chemical cartridge respirator may be required. The necessary requirement is to provide local ventilation in sufficient volume so as to maintain exposures below permissible exposure limits.

To ensure the safety of any on-site refinishing operation, it is necessary to determine how much of the applied material escapes into the surrounding atmosphere, and to further determine the volume of fresh air available into which this material can escape. Since the No. 2 Process handgun is essentially 100% efficient, no solid residue exists to be taken into account. Only the solvent component of the material is released by evaporation into the air at the time of application. The effect of this material must be considered.

A typical on-site application might involve the refinishing of 15 four drawer file cabinets in a space which is 20 feet by 20 feet with a 10 foot ceiling (4,000 cubic feet). This would require approximately 1 gallon of paint applied at a rate of about one-half gallon per hour.

Our coating mixture contains ~59% solvent by volume. One gallon of this type of solvent expands upon evaporation to approximately 27 cubic feet of vapor. Thus, the use of 1.03 gallons of paint could potentially generate 16.5 cubic feet of solvent vapor (1.03 X 0.59 X 27 = 16.5).

If the volume of air where application takes place is 4000 cubic feet as described. Then the solvent concentration in the room without the addition of any ventilation or outside air is 0.41% by volume (16.5/4,000 X 100). This is well below the 1% LEL recorded for the most hazardous normal paint solvents. In this case, a safety factor of 2.4 exists.

If the air in the room is changed only once each hour (66 cubic feet per minute of fresh air is introduced), an additional safety factor of two is provided. As most buildings in which on-site refinishing takes place are air conditioned or have some other manner of introducing ventilation, it can be reasonably assumed that providing for adequate ventilation is not a common problem.

It should be noted that even with this low concentration of solvent in the air, the smell of the paint will still be very noticeable. Especially, since it is not an everyday odor in office buildings. Many people smell the odor of the paint and incorrectly assume a hazard exists. Regardless, it is generally most convenient for the customer to have the work performed after normal business hours so as the smell dissipates overnight.
