Working and breaking time; - Woman’s working and protection time; - Personal protective equipment; - Insurance and assurance • Improve working condition for workers: - Apply modern construction technology and machinery, limit the manual construction work - Prevent labours form hazardous element - Perform risk management STUDENT: HOANG XUAN THIEN LONG 136 C0NSTRUCTION ORGANIZATION PROJECT • Comply with technical standards in construction, safety diary is required Carry out completed statistics, declaration, investigation and analysis of causes of labour accidents • Regulation for labours: - Employees must apply working requirements such as age, gender, health, experience level, and certificate of health and safety in construction - Protective equipment and tools must be equipment - Alcohol is prohibited • Warning sign: - Signs for dangerous (hazard symbols) must be in visible and unobstructed position - Danger signs must be universal to understand - The use of hazard symbols is often regulated by law and directed by standards organizations • Ensure living condition for workers on site: WC, bathroom, restroom, clinic, quality of food and water, etc • Limit population to environment around the site: - Limit the harmful emissions such as dust, noxious gases and noise; - Limit the waste during construction; - Washing bridge must be made at the gate of the site; - Assign a crew to clean areas inside and around construction site • Ensure construction works have no effect to residential areas and existing facilities on site • In addition, safety control must conform to - TCVN 5308-1991 – Code of Practice for building safety technique - QCVN 18:2004/BXD – National technical regulation on Safety in Construction Particular item for safety control is as follow: No Anticipated STUDENT: HOANG XUAN THIEN LONG Prevent action 137 C0NSTRUCTION ORGANIZATION PROJECT accident General Downfall Accident Accident by crane Traffic Accident Electric Accident Others - Prior to starting construction, a joint meeting with relevant staffs must be held for the purpose of general explanation on whole contents of works - Safety guard must be set - Safety belt and equipment must be used for working at high elevation - Covering must be executed around the building to protect materials from falling - The weight of materials to be lifted must be confirmed - Working radius and nominal lifting capacity of crane must be checked as well - Sling tool (wire, cable, shackle, etc.) must be checked daily Its capacity must be confirmed before using - Ensuring the stability of tower crane’s base - Keep out under lifting material - Limited speed on site is 20km/h - Vehicles will move with assistance by signal - Signalman must be set at the entrance of site - Adequate earthing must be installed for electric equipment - Welding work must be carried out with appropriate personal protective equipment (facemask, rubber boots and glover, etc.) Dry area is required for welding -
