Common hazards in the refractory industry include: objects collapsed, objects collapsed, falling, falling, hit, dust, noise and other hazards
One, ergonomic stress and biomechanical hazards
(A) of the source: manual handling materials for too long, too much force, bad posture, high frequency
Keep working, including lifting, pushing or pulling.
(B) the potential effect: back, upper limb and lower limb skeletal muscle strain, sprain and injury, body
And mental fatigue caused the second accident error.
(C) preventive measures and control measures:
1. Assess the job needs of the body.
2. Adjust the design / organization of the job.
3. Use material handling equipment, including: down booster, electric car.
206
4. Adopt automated or semi-automated process.
5. Conduct appropriate technical training and education.
Second, the noise
(A) hazards: pneumatic vibrators, compressors, valve drives, mixer drive motor,
Molding machines, mechanization processes and packaging equipment.
(B) the potential effect: cause occupational hearing loss, communication difficulties and pressure.
(C) preventive measures and control measures:
1. Sound insulation, closed, silencing, reflection or use of sound-absorbing material.
2. Improved machine protection to reduce noise.
3. Use a low noise motor or device (such as a silencer).
4. Install the muffler at the air pressure port.
5. Use hearing aids to develop a hearing protection plan.
Third, the radiation heat and high temperature working environment
(A) Hazard Source: In the maintenance or tunnel kiln heating process.
(B) the potential effect: physiological tension, hot or hot burns.
(C) preventive measures and control measures:
1. Use a protective screen, shield, partition, reflector to heat.
2. Water cooling equipment jacket.
3. Take air conditioning control or closed.
4. Wear anti-heat clothes, gloves or water-cooled work clothes.
5. To adapt to the hot work of the ring, add water or electrolyte drinks, control work - rest time,
As well as other management practices that can cope with thermal stress.
Fourth, the inhalation of raw materials produced by suspended particles, including: crystalline silica, clay, lime, iron oxide,
Harmful dust.
