In the same way, two different methods are possible to ensure the dust-tightness or the dust protection of the enclosure of the apparatus ... 

The type of dust protection according to IEC 60529 may be reduced to IP 20 for parts in intrinsically safe circuits... 

In dark clouds the dust protects the molecules from dissociation by UV radiation. This protection is presumably even better in the case of Scoville s black... 

Dust protection covers should be installed where grease fittings are used. 

PERSONAL PROTECTION Wear clothing suitable for dust protection, including gloves, coveralls, pants, and jacket wear safety goggles suitable for dust protection enclose operations and/or use local exhaust ventilation at site of chemical release wear suitable respira-tory protection, including self-contained breathing apparatus provide safety showers and eyewash fountains in immediate work area. 

Dust protected. Prevents Ingress of dust sufficient to cause harm. 

Removal of construction barriers and ceiling protection may require temporary dust protection to be determined at final project review. 

Head protection must be worn at all times. In all heavy construction areas, required foot protection includes steel-toe shoes with heavy-duty soles to help prevent crushing and penetration. Flaggers are on their feet most of the time, so their shoes need to fit well and be comfortable. Hearing protection includes earplugs or high-tech ear-muffs. For safety reasons, every worker should be able to hear the muted sounds of the construction site—and they should never wear headphones or headsets plugged into a music audio device. And don t forget a face mask for dust protection. 

Areas where lead will be disturbed must be separated from the rest of the house to avoid contaminating other areas with lead dust. Protective clothing and properly fitting respirators must be used. Dry scraping is particularly hazardous. But wet scraping should not be done near electric circuits, even if they have been deenergized.

BS 6467 has two parts. Part 1 is a specification for the apparatus and recognises two categories IP5X dust-protected, which allows some dust penetration but the quantity is insufficient to cause an ignition, and 1P6X dust-tight, where no dust penetration is permitted.
