Safety activity system before shift

In order to implement the safety policy and requirements of "safety first, prevention first", "safety for production, production must be safe", to timely find hidden dangers, eliminate hidden dangers, to ensure the normal operation of construction (production), the construction team pre-shift safety activity system is established.

1, the construction team leader, according to the construction day (or stage) work content, to all workers in the group to make safe operation.

(1) Safety self-check must be carried out before work.

(2) is the working environment and working face safe? Is the protective equipment safe? If the safety hidden danger is found, it must be rectified and eliminated, and reported to the safety officer and construction worker, to be recorded.

(3) Personal protective equipment must be equipped according to the work needs. Workers working at height must wear safety helmet and safety belt, and slippers and hard-soled shoes are prohibited to work.

(4) Do not drink, sick to work, if there is, must be replaced.

2. Each team and group shall carry out safety mutual inspection, so as to supervise each other and jointly observe rules and regulations, especially for the occasion of cross-operation of the team and group, more attention should be paid to it.

3, safety handover inspection system: after the last process is finished, before handing over to the next process, the site responsible person should organize the construction staff, quality assurance staff, team leader and other relevant personnel to participate in the safety inspection or acceptance, confirm no error or qualified, before handing over to the next process.

4. Team safety activities must be recorded as required.

Temporary fire safety provisions

1. Temporary fire must be filled in the application form for temporary fire work in key parts by the fire person (welder), and then submitted to the project leader for approval before the temporary fire work permit is issued.

2, approved by the fire of important departments, before fire to do "eight no", fire to do "four to" after fire to do "one clear".

Do the "eight no" before the fire:

(1) Fire prevention and fire extinguishing measures are not implemented.

(2) The surrounding flammable sundries are not removed and do not fire.

(3) Flammable structures that are difficult to move nearby will not ignite without taking safety precautions.

(7) When welding or cutting at high altitude, the combustible items below are not cleaned or protective measures are not taken.

(8) Fire shall not be ignited without corresponding fire extinguishing equipment.

In the fire to do the "four" :

(1) In the fire to designate the site safety person in charge.

(2) Site safety and fire personnel must often pay attention to the fire situation, found unsafe signs, to immediately stop fire.

(3) In case of fire and explosion, timely rescue should be carried out.

(4) Fire personnel should strictly implement the safety operation rules.

After fire to do "a clear" : that is, fire personnel and site safety responsible person after fire, should thoroughly clean the site fire before leaving the site.

3. Report to the responsible department of the project and return the Temporary Permit for Hot Work after the completion of hot work.
