Safety Devices that Protect Workers From Exposure to Hazardous Subtances from the Workplace

Respiratory protection devices are safety devices that protect workers from exposure to hazardous substances coming from the workplace. Rough dust from grinding, metal powders, toxic and fine dust from smoke and physical painting of buildings, the pungent smell of welding, to steam or toxic gas. These substances can be minimized by using a respiratory or a familiar mask. Before starting work, first identify what contaminant substances are in the work area, as this will be related to the respirator to be used. If fine dust particles are the result of dominant building work, choose a mask that can filter out fine dust. The website provides a list of the best respiratory masks that can be used to protect yourself from dust.

Of course, the masks used by construction workers are different from the usual masks used. In addition to different manufacture base materials, the masks we normally meet, are generally used to filter out lighter dust or smoke, such as street dust for example. Whereas in construction workers, dust or smoke that arise contain heavier particles.

Occupational Safety and Health Administration (OSHA), there are four types of masks suitable for use in the workplace, namely particulate respirator, chemical cartridge/gas mask respirator, powered air-purifying respirator, and the last self-contained breathing apparatus. But the most commonly used by construction workers is a particulate respirator. Particulate respirators are used to protect workers from exposure to dust particles, metal dust, fog, and smoke. Particulate respirators are used to purify air from air suspended particles (aerosols). The filter of this respirator works by capturing particles or aerosols from the air by a filtration method so that air passing through the respirator is clean of these harmful particles.

Generally, the type of mask that has specification particulate respirator is dust mask and N-95. The N-95 mask is a mask that is specifically used for dust exposure with particle size to below 0.1 microns. This type of mask already meets the standards for exposure to silica dust.
