What are the safety precautions in tank fabrication?

Tank fabrication involves high-risk operations such as cutting, welding, and heavy lifting, which require strict safety management and standardized operations to prevent safety accidents, protect personnel safety and equipment integrity. The following are key safety precautions covering all links of tank fabrication.

1. Personal Safety Protection

All personnel involved in tank fabrication must wear appropriate personal protective equipment (PPE) in accordance with operational requirements. Welders must wear flame-retardant overalls, welding gloves, protective goggles, and face masks to prevent burns, electric shocks, and eye injuries from welding sparks. Operators engaged in cutting, grinding, or derusting work should wear dust masks, safety glasses, and anti-cut gloves to avoid inhalation of dust and injury from debris. Personnel working at heights must wear safety belts and use stable scaffolding or aerial work platforms to prevent falls.

2. Workshop Safety Management

The fabrication workshop must maintain a clean, tidy, and unobstructed environment, with clear division of operation areas and safe passages. Flammable and explosive materials (such as welding rods, solvents, and paint) must be stored in a dedicated, ventilated, and fire-proof warehouse, separated from ignition sources (such as welding equipment) by a safe distance. The workshop should be equipped with sufficient fire-fighting equipment (fire extinguishers, fire hydrants, sand buckets), which must be regularly inspected and kept in good condition. No smoking or other illegal ignition behaviors are allowed in the workshop.

Ensure good ventilation in the workshop, especially during welding, painting, and derusting operations, to discharge harmful gases (such as welding fumes, paint volatile gases) and reduce the risk of poisoning. Install gas detection equipment in areas where flammable or toxic gases may accumulate, and take emergency measures immediately if the gas concentration exceeds the safety limit.

3. Equipment Safety Operation

All fabrication equipment (cutting machines, welding machines, rolling machines, cranes, etc.) must be inspected and debugged before use to ensure they are in normal working condition. Operators must be familiar with the equipment’s operating procedures and hold corresponding operation certificates; unauthorized operation of equipment is strictly prohibited.

Welding equipment must be grounded reliably to prevent electric shocks. Check the integrity of welding cables and connectors regularly to avoid short circuits or electric leakage. Lifting equipment (cranes, hoists) must be inspected for load-bearing capacity and safety performance before use; lifting operations must be directed by a dedicated person, and overloading, slanting lifting, or hanging of unstable components is prohibited. After use, equipment must be shut down, powered off, and cleaned and maintained regularly.

4. High-Risk Operation Safety

Welding and Cutting Operations: Before welding or cutting, check the surrounding environment to remove flammable and explosive materials within a 5-meter radius; if it is unavoidable, take effective isolation and fire prevention measures (such as laying fire-resistant blankets). During operation, ensure that the welding current and voltage are within the safe range, and avoid welding near flammable pipelines or containers. After operation, check the site carefully to confirm that there are no residual sparks or smoldering materials to prevent fire.

Confined Space Operation: If tank fabrication involves confined space operations (such as internal welding or inspection of tank bodies), strictly implement confined space operation procedures. Before entering, conduct gas detection to ensure the oxygen concentration, flammable gas concentration, and toxic gas concentration meet safety standards. Arrange a dedicated person to monitor outside the confined space, and maintain continuous ventilation during the operation. Equip emergency rescue equipment (such as rescue ropes, air respirators) on site to deal with emergencies.

High-Altitude Operation: High-altitude operation platforms must be stable and reliable, and safety nets should be installed if necessary. Tools and materials used at heights must be placed firmly to prevent falling and injuring people below. Avoid high-altitude operations in severe weather (strong winds, heavy rain, thunderstorms).

5. Electrical and Fire Safety

The electrical system in the workshop must comply with national electrical safety standards, and all electrical equipment and lines must be installed and maintained by professional electricians. Avoid random wiring or overloading of electrical circuits to prevent short circuits and fires. In wet environments or areas with high humidity, use waterproof electrical equipment to prevent electric leakage.

Formulate emergency fire plans and conduct regular fire drills to ensure that all personnel are familiar with fire-fighting equipment usage and escape routes. In case of fire, cut off the power immediately, use appropriate fire-fighting equipment to put out the fire, and report to the relevant departments in a timely manner.

6. Safety Training and Emergency Response

Regularly conduct safety training for all fabrication personnel, covering operational safety norms, hazard identification, emergency handling skills, and PPE usage. New employees must receive pre-job safety training and pass the assessment before taking up their posts. Conduct regular safety inspections and hidden danger investigations, and rectify any found safety hazards in a timely manner.

Establish an emergency response mechanism for accidents (such as fires, electric shocks, falls, and gas poisoning). Equip emergency rescue equipment and first-aid kits on site, and train personnel in basic first-aid skills. In case of an accident, stop the operation immediately, rescue the injured, and take measures to prevent the accident from expanding, then report the accident truthfully according to the procedures.
