Personnel Hazards of Dry Chemical Systems - Essay Example

Since the fire-extinguishing agent is in the form of fine particulates, the main concern is the inhalation of dust particles. This is especially the problem in total flooding than in local applications. Dry chemical systems that include mica, clay, and amorphous silica can contain small quantities of quartz or crystalline silica. Inhalation above the exposure limits (about 3 mg/m3) and prolonged respiratory exposure can increase the possibility of developing a disabling disease called silicosis.

The condition induces inflammation and scarring of nodular lobes in the lungs. It can induce chronic coughing and fever. Deposits of crystalline silica were also identified as carcinogenic to the human body through this is yet subject to further verification. Decompositions of compounds also include hazardous products such as ammonia, carbon oxides and phosphorous oxides. These can induce negative health effects such as fever and respiratory problems. Dry chemical compounds are also extremely corrosive and abrasive to metals indicating that it can also cause skin diseases like dermatitis and other complications to eyes and other parts of the body.

However, many dry chemicals in the market do not require extensive protective equipment, especially in local applications. There is also the possibility of explosion of pressurized containers though this is quite unusual but possible. (Acme Fire, 2007)
