Health Risk Assessment:
- All the above operations shall be executed strictly in accordance with Project Occupational Health, Safety, Security and Environmental Plan.
- Prior to the commencement of any activities, the workforce will receive a safety induction on the project site safety requirements; this safety induction will include Project HSE Policy, Project details and layout, Site management team, general site HSE requirements, emergency procedure including Emergency contact numbers, Roles and responsibilities of the workers, Site discipline, general environmental awareness, PPE requirements.
- The HSE roles and responsibilities shall be delivered to all staff (construction manager, engineer, supervisor, foremen, and charge hand).
- Work will commence as per safety regulations laid in the contract specifications and project safety plan.
- Housekeeping shall be of good standard and debris shall be removed.
- All activities will be performed according to the control measures and instructions prescribed in the attached Risk Assessment Sheets.
- Daily JSA will be done before the commencement of each shift and each new task.
- All Vehicles will have valid licenses and passes before entering the site.
- PPE shall be issued to all personnel (Mandatory PPE’s: Hard hat, Safety glass, high visibility vest, Safety shoes and cover all. Task specific PPE; Dust mask, goggles, hand gloves).
- Specific training shall be given for task specific tools and equipment’s; records shall be kept in HSE department.
- Heat stress training will be provided during summer time, records shall be kept in HSE department.
- Adequate cool drinking water, shade and hydrolyte shall be placed.
- Plant and equipment shall have back up alarms, lights and all other applicable safety devices.
- Provide Banks man when operating equipment reverse and moving the equipment where pedestrian movement is exist.
- Work on site will be supervised by a competent person (Qualified SE)
- Safety Lighting
Emergency Procedures:
- Contact numbers of personnel concerned to be displayed.
- Emergency response team to be designated and on standby:
- All emergency contact people are posted around the project and are being discussed during site safety meeting.
- Emergency routes and exists to be clearly marked.
- 1 vehicle with one driver will be available for any emergency.
- Requirement of the Project Emergency Preparedness and Response plan shall be strictly followed.
- In the event of an accident, contact the area HSE Supervisor.
- In case of Diesel Spillage contact the Environmental department.
- Easy means of access will be available at all time.
- Contact numbers of all emergency supervisors will be distributed to site personnel (Site engineer, Safety officer, male nurse and concerned authorities and emergency services).
- Injuries will have the highest priority to be directly dealt with at once.
- There are different types of situations that we need to consider under this section. These are:
- Basic first aid
- Medical
- Property damage
- Environmental releases
- Fatality
- Fire
- The nominated response team will consist of:
- Site nurse
- Safety Engineer/Officer
- Site Superintendent/Foreman
- 4no of operatives
- Basic first aids
- The injured person, if mobile, can make his way to the site clinic for treatment by a qualified site nurse that is available and logged in the first aid register.
Medical:
Under this section, there are two categories that we need to consider. They are as follows:
(1)- Conscious
If the patient is feeling un-well, he will immediately inform his supervisor and go to the site clinic to be assessed by the site nurse. The site nurse will then advise, or the patient will require further examination and he will be taken to the hospital.
(2)- Unconscious
If the patient had collapsed during his work, alarm must be raised to inform the response team. The team will then respond accordingly by the quickest possible way arriving at the location of the incident. Along with them, they will bring a first aid kit, an emergency stretcher and an emergency vehicle. Once they are on the scene, the site nurse will assess the patient and the team will then take the patient on the stretcher either to the site clinic or to the local hospital.
- Electrocution:
- If you see someone lying unconscious or “froze on the circuit,” the very first thing to do is shut off the power by opening the appropriate disconnect switch or circuit breaker. Don’t touch another person being shocked, If the power disconnect switch cannot be located quickly enough, it may be possible to dislodge the victim from the circuit they’re frozen on to by prying them or hitting them away with a dry wooden board or piece of nonmetallic conduit.
- Once the victim has been safely disconnected from the source of electric power, the immediate medical concerns for the victim should be respiration and circulation (breathing and pulse). Call nearest First aider to apply first aid to the electrocuted person. If a victim is still conscious after having been shocked, they need to be closely monitored and cared for until male nurse arrives.
- Rescue from Height:
- There will be rescue team with emergency rescue kit readily available at site in case of “Rescue from Height” is needed. The rescue team members are chosen from scaffolding team that has no acrophobia and has enough experience on working at height.
- Emergency response drill should be conducted as per Project Emergency Drill Schedule.
- Only the competent personnel will be allowed to install the system who has experience and trained by the supplier.
- Environmental:
- Working areas will be kept free as practicable from construction debris and equipment’s which are not actually in use.
- Proper access to the work areas should be maintained all the time. Particular attention to be paid to environmental hazards such as excessive dust emission, excessive noise from equipment, unpleasant odor of material or chemical to be used, etc. Hence a corresponding control measure will be performed as below mentioned but not limited on it:
- Water spraying for dust control
- Noise level monitoring
Complied with the materials safety data sheet recommendation regarding environmental aspect/impact of the material to be used.
