Ear Muffs: For those working near the crusher
and at loading points where frequent dumping
of the boulders is taking place. They need to
be washed regularly
Ear plugs: For those working in the distal
vicinity at the time of crushing activity. They
need to be washed and changed regularly
Putting in ear plugs correctly
A.3.5 Working Safely at Night
Lighting is important in the workplace not only for worker comfort but also for safety reasons. Good
lighting is needed throughout the plant and yard but specifically at access roads, at the boulder loading
point at the top of the primary crusher, and at delivery points. Truck drivers, for instance, need to see
their environment, the road and other workers.
Illumination refers to the quantity of light in a certain area. A lack of illumination may make specific and
general tasks both difficult and dangerous for workers
Common unsafe conditions or acts
−
Poor illumination at night and uneven light distribution
− The glare from high intensity lighting is a concern; as the glare is increased by the dust and white
stones as well as from reflective metal sheets often strewn around the site
Hazards and health risks
− Any kind of accident can and will occur when lighting is not sufficient: trips and falls or vehicle
accidents Cost effective lamps such as sodium vapor lamp or mist/dust diffusing lights are
available for stone crushing units
Solutions to protect health
Ensure a good amount of lighting at the pit area and on the access areas. You can also
conduct a survey on the continuous, frequent and occasional activity areas and provide lighting
accordingly
Focus the light on crusher operations
Enough lighting at night time should be ensured by providing street lights and focused light to
cover the entire area
Ensure a torch light is also provided to workers at the top of the boulder pit for emergency use
Ensure an illumination of a minimum of 150 lux around the crusher area and 200 lux projected
as a spot light on the crusher itself. "Lux" is the unit in which light is measured. You might
need the help of an occupational health expert or technician to determine appropriate and
cost-effective light fixtures
