Protective clothing is to protect the body of the worker while dealing with chemical or biological compound. Different type of aprons (rubber, plastic or PVC) give different levels of protection to the body. When dealing with combustable material, fire-retardant type of apron or other mean of protective clothing need to be used. Street clothing that covers the arms, legs & trunk of the body and/or laboratory coats must be worn when working with chemicals. Laboratory clothing that has been contaminated must be removed immediately and, in certain circumstances, disposed of properly. A protective glove is used to avoid the contact of chemical (corrosive or toxic) or specimen with the workers fingers/hands/skin/arms since some of these compound can cause irritation, dermatitis or even burn.

Face shield is a device to protect the eye and faces of the wearer while dealing with laboratory work such as burning test of chemical compounds, such as magnesium. Safety goggles with side shields or a face shield are required where there is a risk of eye damage from flying projectiles involved in a task like grinding, construction or agricultural activities. Working in an environment with multiple risks requires wearing safety goggles and a face shield. Contact lenses are discouraged for laboratory work. Impact resistant face shields must be worn when handling explosive chemicals. Working with liquid nitrogen and operating vacuum equipment or steam sterilizing equipment pose risks of explosive breakage. Wearing an impact resistant face shield is recommended. When working with explosive chemicals or certain radioactive materials, free-standing safety shields are required. High-quality face shields should be optically clear, distortion-free and 7mil film thick. Polyester lens is treated with antifog and antistatic coating. The headpiece is held in place by a stretch strap and includes a latex-free, hypoallergenic foam band for comfortable extended wear.

Mats provide added protection in areas requiring a greater degree of contamination control. Adhesive mats have a ten adhesive-coated, closed-cell disposable polyfoam sheets, pick up more contaminants & last longer than conventional mats. Moderate tacks, sheet pull-tabbed for easy peel-off removal. Adhesive mats with plastic frames are double contoured & facilitate easy & trip-free movement of personnel & wheeled equipment on and off surface. Refill mats are easy to install-simply remove the protective paper from the adhesive strips on the bottom & press onto the cleaned floor. Hard surface adhesive mats are useful for sanitary conditions in cleanrooms. When the top sheet becomes soiled, just peel it off to expose the fresh clean surface. Reorder notification is provided on the 18th sheet. Adhesive entryway mats trap contaminating dirt, dust & bacteria before they invade cleanrooms. They are 2mil thick polyethylene sheets coated with environmentally friendly waterborne acrylic adhesive. A pull-tab system makes it easy to peel off the top sheet when it becomes soiled, the remaining sheets stay intact and clean. It will not curl, tear or wrinkle and the adhesive will not transfer to footwear. It is treated with an antimicrobial agent.

Protective proteins in the body aid the immune system in determining which cells are harmful and which are normal and healthy. As the immune system patrols the body for biological troublemakers, it regularly strikes out at normal, healthy cells as well. Cells rely on special protective proteins to avoid being the victims of this friendly fire. Two of these tiny bodyguards--called MCP for membrane cofactor protein and DAF for decay accelerating factor--also may help sperm fertilize eggs and protect sperm in the female genital tract. In addition, scientists are looking for ways to recruit MCP and DAF to tell the immune system what to kill and what to leave alone. This research eventually could affect cancer therapy, organ transplantation, and treatments for a wide range of inflammatory diseases.
