Hazard Identification and Safety Measures of Printing Factory

The printing factory is a place with dense dangerous sources, so the safety problem can not be ignored, otherwise safety accidents will occur, resulting in casualties and huge economic losses.

Hazard identification

1. Fire

A large number of raw and auxiliary materials used by printing enterprises, such as paper, ink, cleaning agent, etc. Flammability is the main hazard of printing house.

2. Danger of equipment operation

Printing, paper-cutting, bookbinding and other mechanical equipment run fast and transmit high energy. Some equipment has a wide working face, and illegal operation is easy to cause limb injuries.

3. Electrical hazards

(1) static electricity

High-speed printing machine will produce high-voltage static electricity when it runs at high speed, which may lead to air discharge, electric shock or fire in serious cases.

(2) Electric leakage of wires and cables

Aging or damage of insulation layer will electrify equipment or other contact conductors, and people will get an electric shock if they touch it.

4. Hazardous chemicals

Volatile dry ink, cleaning agent, gasoline and other flammable and toxic chemicals may be used in printing or post-press treatment, which will endanger the health of operators and may cause fire.

5. Noise hazards

The operating noise of machinery and equipment in the production workshop is relatively high, generally at 70 ~ 100 dB (A), mainly mechanical noise and electromagnetic noise. Working in noise for a long time is not good for the physical and mental health of the operator.

6. Other environmental hazards

Unsafe working environment such as occupied working channel, unclear or lost safety signs are also factors that cannot be ignored.

safety measure

1. Fire control

(1) The workshop meets the fire protection standards.

The workshop of printing enterprises should meet the fire protection standards, and the fire safety characteristics of the workshop should be analyzed by scientific performance evaluation method, so that the workshop must meet the minimum requirements of fire safety while meeting the production requirements.

(2) Wires and cables meet the fire protection requirements.

Standard fire-resistant cables and flame-retardant cables should be used. It is forbidden to use electricity in overload, and it is forbidden to connect electricity without permission or use electricity unsafe.

(3) Establish a fire alarm and monitoring system.

Establish a fire alarm and monitoring system, when the monitoring parameters exceed the standard, automatically alarm and start the corresponding facilities to reduce the fire risk level.

2. Prevent dangerous operation of equipment.

(1) Strict operating procedures

Select printing machines and other equipment that meet the safety standards, ensure that the protective devices of the equipment are in good working condition, and stop the equipment that is not operating normally for maintenance.

(2) Serious labor discipline

Employees should improve their safety awareness and consciously abide by safety production laws and regulations.

At the same time, it is necessary to establish and improve the labor safety inspection system and conduct regular safety inspections.

3. Measures to prevent electric shock

(1) antistatic

Equipment prone to static electricity should be equipped with supporting facilities to eliminate static electricity, strictly control the ambient temperature and humidity of the printing workshop, and regularly eliminate static electricity in the workshop and equipment. Operators in areas prone to static electricity should wear special anti-static clothing.

(2) to prevent electric leakage of wires and cables

The equipment should have correct grounding protection, wires and cables should avoid the only way for personnel, aged and damaged cables should be replaced in time, and live maintenance should conform to the operating specifications.

4. Safe use of chemicals

Establish and standardize the purchase, storage, transportation and use system of hazardous chemicals, and formulate reasonable emergency plans in combination with production technology.

Step 5 control noise

Install sound insulation and noise reduction facilities for major noise equipment; The workshop walls are made of sound-absorbing materials to reduce reverberation caused by reflection; Take corresponding individual protective measures.

6. Eliminate environmental hazards

The enterprise environment should embody the people-oriented thought and realize the harmonious unity between people and the environment.
