Due to the cold weather in winter, which can easily cause dangerous accidents, Xingtai Huanri Rubber and Plastic Products Co., Ltd. conducted a special safety production training in December 2023.

 

The training mainly explained the common problems encountered in winter and how to prevent them.

safety problem

 

01.Anti freezing and cold protection

 

The weather is cold, and people are prone to frostbite, stiffness, and lack of sensitivity. Equipment and metal structures are prone to deformation, rupture, and leakage, leading to further disasters.

 

In winter, employees should pay attention to keeping warm and preventing frostbite. However, heavy clothing can cause inconvenience to movement, and inappropriate clothing can even pose a danger. Wearing a long coat can easily get caught and cause injury near the transmission equipment. It is not advisable to wear a coat or scarf during work.

 

When hands are damp, do not touch the steel to avoid frostbite. Take measures to prevent freezing of pipes (water pipes, fire hydrants, and drainage systems) and prevent the occurrence of frozen pipes.

 

Regularly inspect the sealing components of pipelines and equipment, and prohibit thawing with open flames. It is recommended to use hot water for thawing.

 

02.Anti slip fall

 

In winter, there are more rainy and snowy weather, with lower temperatures, making objects hard and brittle. The ground is slippery and wet, and due to early darkness, the fog seriously affects vision, making it difficult to move flexibly and prone to accidents such as slipping, falling, and object impact.

 

 

Before starting work, promptly remove accumulated water and snow from the ground. People and vehicles should avoid walking on ice, and vehicles should slow down.

 

After frost and snow, when climbing stairs, one should grab the handrails of the guardrails and wear gloves. If it freezes, it should be cleaned up in a timely manner.

 

Ladders, climbing platforms, scaffolding, scaffolding, etc. should be kept dry and should not be placed outdoors in rainy or snowy days to prevent frost and ice formation.

 

Before transporting and lifting the suspended object, it is necessary to check whether the object is wet and whether there is frost or ice. After confirming completion and the lifting test is normal, the lifting can be carried out.

 

Frost and ice form on the steel plate, and employees are not allowed to walk on the steel plate.

 

03.Prevent poisoning and suffocation

 

In winter, with low air pressure and poor ventilation, it is easy to accumulate toxic, harmful, flammable and explosive gases, which can lead to poisoning and suffocation in daily life or occupation during heating, cooking, and production operations.
Due to the cold weather and the principle of thermal expansion and contraction, the welds and valves of the trachea are prone to freezing and cracking, resulting in gas leakage and accumulation of dead corners, which poses a risk of suffocation for personnel.

 

 

Ensuring the safety of confined space operations is the key to preventing suffocation:

 

Before starting work, ventilate and exchange air in advance. Only after passing the inspection and approval can one enter the confined space for work;

 

During homework, maintain good ventilation and set up guardians nearby. Guardians are not allowed to leave their posts;
After homework, pull the trachea out of the limited space and turn off the air source.

 

 

It is strictly prohibited to use wood, coal balls, and other materials for daily heating.

 

 

04. Anti electric shock

 

 

In rainy and snowy weather, the air and ground are humid, and the insulation performance decreases accordingly. Leakage of equipment, power lines, and other components can cause a risk of electric shock to personnel.

 

 

Before each power transmission, it is necessary to carefully check whether there is water accumulation in the equipment location, whether the power cord is damaged, and strictly prohibit power transmission until the water accumulation is cleared.

 

 

The door of the electrical box should be kept in a normally closed state, and if necessary, waterproof measures should be taken to prevent water ingress, moisture ingress, short circuits, and equipment damage.

 

Properly store the equipment and tools after use, and keep them out of reach of rain and snow to prevent accelerated insulation aging.

 

05. Preventing electrical fires

 

High power heating appliances are commonly used in winter, resulting in overloading and illegal use of electrical equipment, leading to fire accidents.

 

Overloading electricity can cause overheating of the circuit, leading to ignition.

 

Do not use electrical appliances prohibited by the company for heating, and do not dry clothes on heating appliances.

 

The socket under the office desk is likely to have a lot of dust and aging wires, and should be checked and replaced in a timely manner.

 

 

The distribution box in the dusty area should be cleaned daily by blowing dust to prevent dust accumulation from causing short circuits in the wires.

 

 

Electric fire shall not be extinguished with water or foam extinguisher.

 

Firstly, the power should be cut off and sand, dry powder fire extinguishers should be used. For valuable and precision equipment, it is recommended to use carbon dioxide fire extinguishers.

 

 

Winter is dry and often accompanied by static electricity. Places storing flammable and explosive materials should take anti-static safety measures.

 

 

06. Prevent extreme weather

 

 

In winter, there is often a significant drop in temperature, accompanied by extreme weather, which brings trouble to safety production. In windy weather, outdoor high-altitude operations should be reduced.

 

When encountering weather such as rain, snow, hail, etc., personnel should pay attention to safety; Materials and equipment stored outdoors should be protected to prevent damage.

 

 

07. Preventing unsafe psychology

 

Lucky mentality, numb mentality (strictly following regulations), opportunistic mentality, careless mentality, and reckless mentality.

 

 

08. Property security

 

Pay attention to phone scams, keep valuables hidden, travel together, and lock doors and windows when going out.

 

 

 

Usage of fire extinguishers

 

Instructions for using dry powder fire extinguishers:

 

1. Pull out the insurance pin;

 

2. Lift the fire extinguisher to the right and press the handle;

 

3. Hold the nozzle tightly with your left hand and aim it at the root of the fire source.

 

When using a portable dry powder fire extinguisher, it should be carried out at a distance of about 3-5 meters from the combustion object.

 

The operator should first shake the fire extinguisher up and down, then remove the safety pin on the opening handle, and then hold the root of the nozzle in front of the spray hose with one hand, and press the opening handle down with the other hand.

 

Quickly aim at the root of the flame and spray dry powder to extinguish the fire.

 

 

When extinguishing the fire, it should be done quickly and thoroughly, without leaving any residual fire to prevent reignition.

 

Use method of foam extinguisher:

 

When using a foam extinguisher, people should stand upwind and try to be close to the fire source, because its spraying distance is only 2-3 meters.

 

 

It should be sprayed from the side where the fire spread is most dangerous, and then gradually move, taking care not to leave sparks. Grasp the wooden handle of the nozzle with your hand to avoid frostbite.

 

 

Due to the excessive content of carbon dioxide in the air, it is also harmful to the human body. Therefore, in situations where the air is not unobstructed, ventilation should be provided immediately after spraying.
