What are the safety precautions for winter construction?

It is very important to pay attention to the safety precautions for winter construction. The precautions are formulated for better construction results, and every detail is well-founded based on the actual situation. Zhongda Consulting will explain to everyone the safety precautions for winter construction.

(1) General provisions

1. Regularly conduct technical safety education for all construction personnel on site; make safety technical briefings before winter construction in conjunction with the construction tasks of this project; prepare Safety protective equipment.

2. In winter, protection becomes more difficult. People working outdoors should pay attention to keeping warm and prepare cold-proof and warm supplies and related emergency medicines. When constructing on snowy and icy sites, you should wear non-slip shoes and use sticks to explore the path. Safety protection personnel must stick to their posts to ensure the personal safety of construction workers and the safety of equipment.

3. Carefully prepare the construction site for cold protection. During construction in foggy and snowy days, more protection and lookout personnel should be provided to ensure the safety of driving and personnel. It is necessary to do a good job in preventing slipping, freezing and gas poisoning.

4. During the winter construction process, the project department is required to pay attention to the weather conditions at all times in order to formulate appropriate construction methods according to weather changes. In the event of heavy snow, outdoor construction should be stopped to avoid safety problems caused by unclear vision.

5. When constructing existing lines, wear a safety helmet with ear holes. When working on the upper part, you should wear soft-soled non-slip shoes (note: untied shoes are not allowed under any circumstances).

6. When working on poles or towers, workers who climb the poles must carefully check and stand firm to prevent casualties caused by frost or snow on the poles from sliding.

7. Anti-slip measures must be taken when encountering strong winds of level 5 or above or severe weather such as snow, fog and frost. When the visibility of lighting is unclear at night, it is strictly prohibited to carry out high-altitude operations and hoisting operations. Personnel working at high altitudes Seat belts must be fastened. The seat belts should be hung in a secure and reliable place above the human body and must be hung high or low.

8. All materials, formwork, concrete components, acetylene bottles, oxygen bottles and other storage areas on site must comply with safety requirements and be managed more effectively. All flammable insulation materials should be used according to production needs, and a dedicated person should be responsible for their deployment to prevent backlogs.

9. Chemicals with conflicting properties must not be stacked on the same shelf to prevent chemical reactions from mixing with each other and causing fires. Inflammable items such as straw curtains and polystyrene used for winter insulation should be stacked in a safe place and maintained in a dry and ventilated environment.

10. The ladder truck used for the catenary should be strong and reliable and should be inspected regularly. It should be carefully cleaned and inspected after strong winds and snow, and hidden dangers should be eliminated in a timely manner. Construction workers must abide by regulations and disciplines, and avoid illegal operations, illegal command and risky operations. The ladder truck must be checked for ice and wiped before working at heights.

11. Organize all on-site employees to carry out publicity and education on safety fire protection during winter construction, and formulate specific measures for safe production and anti-skid, anti-freeze, fire and explosion prevention.

12. The canteen focuses on checking for problems such as lack of supervision, overloaded electricity, gas leakage, etc., and does relevant preventive work: first, the installation of electrical equipment and wiring laying should comply with safety regulations; second, there should be no safety hazards near the stove. Do not stack other combustible items. The liquefied gas stove used in the kitchen must be isolated from the stove. Frequent safety inspections must be carried out on the main valve and pressure regulating valve of the liquefied gas stove, and hidden dangers must be dealt with in a timely manner. Third, liquefied gas tanks should be kept away from Fire sources and diners are prohibited from storing gasoline, diesel barrels and other flammable and explosive items in and around the canteen, and it is prohibited to store spare liquefied gas tanks. Fourth, before leaving work every day, staff must carefully conduct safety inspections, close all switches, and cut off the fire. source, air source and power supply to ensure safety. Fifth, necessary fire-fighting equipment should be equipped in accordance with fire prevention requirements and regulations, and should be inspected regularly, replaced on schedule, and drilled regularly.

13. The branch office and project department logistics managers shall, in accordance with the relevant provisions of the "Fire Protection Law", allocate fire-fighting equipment, facilities and fire-fighting signs, establish fire-fighting equipment and facility location plans and fire-fighting equipment ledgers, and important fire-proof parts (Warehouses, carpentry rooms, etc.) Set up fire prevention equipment and obvious fire prevention signs. If it is expired or damaged, it must be replaced in time.

14. Fire-fighting equipment should be kept and stored in obvious and fire-prone areas according to the instructions for use. Regular inspections are required to ensure that fire-fighting equipment is in good condition and effective. Set up reasonable storage locations for flammable and explosive dangerous goods, conduct regular inspections, and correct hidden dangers in a timely manner to nip them in the bud.

15. When setting up pillars and backfilling soil, do not use frozen soil for construction. Strengthen compaction and conduct on-site inspections daily. If there is any settlement of backfill soil, dig up the soil in time. The earth to be used for winter backfilling should be piled in large piles and covered with two layers of straw mats to prevent freezing.

16. During the foundation pouring construction process, it is necessary to conduct temperature tests and slump tests before entering the mold, and record the work. After the pouring is completed, add an insulation layer (plastic sheet, straw curtain, etc.) , to prevent surface frostbite.

(2) Fire management at construction sites and residences

1. There must be dedicated fire watchers at open fire operation sites. The main responsibilities of fire watchers are as follows:

a) Remove combustible materials near the fire site. If it cannot be removed, it can be moistened with water.

b) When welding objects, use asbestos cloth to protect them or use a fire catcher to catch sparks.

c) Fire-fighting equipment must be prepared at the fire site. Always check fire-fighting water to prevent freezing from affecting fire-fighting.

d) Fire watchers are not allowed to leave their posts without permission. After the operation is completed, the fire location should be carefully inspected, especially the area where sparks splashed, to confirm that there is no possibility of re-ignition before evacuating the post.

2. The use of open flames for heating is strictly prohibited at the construction site. Fireworks are strictly prohibited in the key fire protection areas of the material storage area. It is strictly prohibited to carry fire and the use of iodine tungsten lamps for lighting and heating. Complete safety signs to eliminate fire hazards. Fires are not allowed for heating in the warehouse. Smoking and working with open flames are strictly prohibited within 15m.

3. Relevant regulations must be strictly implemented when using fires for heating and open flames. Special measures must be taken for heating by fires, and flammable gas detectors must be installed. It is prohibited to pile up flammable items around fires. To maintain ventilation, the chimney must not be installed upside down and must be effectively fixed. Fireproof material support pads should be used at the exit of the chimney. The dormitory must be managed by dedicated personnel to prevent fire and gas poisoning accidents.

4. Fire equipment at the construction site should be strictly managed according to fire protection requirements, and attention should be paid to indoor ventilation to prevent gas poisoning caused by heating and eliminate fire hazards.

5. Regular comprehensive inspections of fire-fighting equipment should be carried out, and thermal insulation and anti-freezing measures should be taken for fire-fighting facilities.

6. Conduct regular comprehensive inspections of construction and domestic electricity consumption, strengthen electricity management, and ensure the normal operation of power supply equipment and lines.

7. The construction power distribution device must be equipped with a leakage protector, and the temporary power supply can only be connected from behind the leakage protector.
