Hazard Analysis and Preventive Measures of Refractory Materials

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.

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.
