Control Measures

  • Ensure Banks men control all reversing vehicles and vehicles leaving the site.  All vehicles leaving the site should leave in forwarding gear only.  All drivers of vehicles are to abide by site-specific rules about speed restriction etc. i.e., 5mph. On-site pedestrian routes are to be established particularly at the site entrance and where the plant and operatives interface. Lane management is required to undertake the demolition of the buildings abutting the road. Heras’s fencing was used to create an exclusion zone. Banks issued with 2-way radios control traffic flow during active demolition. Only when the machine driver confirms safe vehicle passage will vehicle movements be allowed to pass.
  • All site personnel will wear the minimum mandatory PPE: Hard hat, Hi visibility vest/jacket, safety boots, and gloves.  Other items of PPE such as Light eye protection are also available and will be worn as and when necessary.
  • Make sure to controls and or reduce dust emissions are in place as noted on the safety plan or method statements.  
  • Ensure goggles and suitable dust masks are worn as per the attached PPE Assessment.  Ensure controls are suitable and sufficient to control airborne particulate
  • Establish an exclusion zone/ hearing protection zone, limiting access using barriers and signage.
  • Restrict the number of people in the working zone
  • Certificates are in place.  MEWP is hired from a reputable supplier, and all certifications and records of tests are in place.  Operatives trained and competent in the use of hired equipment. The MEWP is suitable for the task and is located on suitable stable ground. Operatives trained in the use of full-body harnesses.  Operatives wearing full-body harnesses with lanyards. Lanyard is attached to the platform. Operatives carrying out the works from the confines of the platform (do not lean outside).
  • The access tower is securely footed, and stabilizing legs are fully extended as per the manufacturer’s instructions, the access towers have edge protection installed consisting of a main top rail and intermediate guard rail. The main guard rail's height is at least 950mm above the edge, and the intermediate guard rail does not have a gap of more than 470 mm. Toe-boards are fitted they are at least 150mm.
  • A suitable rescue plan and suitable equipment are in place in case of any type of emergency.  All persons involved in a rescue operation know their part and the procedures to follow.
  • Ensure that no asbestos materials are disturbed during any removal of adjacent soft strip materials if applicable.
  • Employ good housekeeping, Safe clear access routes to be identified within and around the structure, these areas must be checked regularly and any hazards identified must be rectified promptly.  The end of the shift ensures all tools etc. are removed.
  • Ensure correct PPE as per the attached PPE assessment.  Good housekeeping.  Safety shoes must have mid-sole protection and toe protection
  • Where services within proximity are required to be left LIVE for the duration of the works, they must be identified, and their location documented before commencement. The site manager must ensure that all operatives and plant operators are aware of their location and the controls that are required to ensure their protection.
  • Strict permit-to-works system in place, the site manager must ensure that all operatives and plant operators are aware of their location and the controls that are required to ensure their protection
  • The site supervisor and machine operator to carry out a walk around the survey. To minimize the risk of overloading the floor materials will need to be cleared regularly, works will be stopped, and the materials cleared from the floor into safety exclusions zones below. 
  • Ensure the physical barriers to prohibit unauthorized persons into the working area are effective. Ensure the warning signs posted are visible. 
  • Ensure all works are carried out following the Control of Asbestos Regulations 2012, all current guidance, and industry best practices.
  • EXCLUSION ZONE: Erect physical barriers to the working area to prevent unauthorized access during the works with signs displayed depicting men at work / or Access Prohibited warning signs.
  • The site supervisor and machine operator to carry out a walk-around inspection of the working area. Ensure any adjacent structures will remain unaffected and safe.
  • Ensure the floor slab has been cleared, is clean, and is free from obstructions. Ensure the slab is adequately dampened before the commencement of the works.
  • Ensure that the machine is large enough to carry out the work at arm’s length and that the machine can reach the required elements of the structure safely.
  • Ensure fiber and dust reduction through pre-wetting, and knockdown water sprays. Clear away cut-down sections progressively. Do not allow tracking or traveling of plant and machinery on asbestos debris.
  • The correct RPE/PPE should always be used (Disposable coveralls (Type 5), Rubber gloves, Safety boots, Sandstrom half-face masks, Glasses, and Hard Hat,). Carry out background and personal air monitoring to ensure control measures are effective.
  • Ensure a dedicated and segregated area is allocated for changing machine attachments.  Ensure the machine operator is fully trained in the use of the quick hitch system on the machine.  Ensure the site supervisor is aware of his responsibility to ensure that all machine operators on site carry out daily inspections on the quick hitch.
  • Ensure the hot work permit system is implemented and signed off at the end of the works.  Ensure firefighting equipment is on hand during all cutting works. Ensure that all cutting operatives are competent in their task and have had sufficient information, instruction, training & supervision. Ensure the permit is signed off.  PPE is to be used as per the attached PPE assessment.
  • All cutting equipment i.e., guns, bottles to be fitted with correct safety valves and flashback arrestors.  Propane to be separated from oxygen by a minimum of 3 meters.  
  • Inspect the surrounding vicinity and remove combustible materials wherever practicable. Spread sand to the area below the cutting area if permissible. Adopt a permit-to-work procedure for all works. 
  • EXCLUSION ZONE: Erect physical barriers and warning signs around/below the area of work. The operative must ensure that the work area has adequate ventilation for the task at hand. To reduce the risk of an uncontrolled fire no hot works must be undertaken within one hour of lunch or the shift ends. Ensure the permit is signed off.
  • Ensure goggles and suitable dust masks are worn as per the attached PPE Assessment.  Ensure controls are suitable and sufficient to control airborne particulates.
  • Establish exclusion zones limiting access into the working zone. All operatives within the working zone are to wear eye protection, hearing protection, and a dust mask. Dust suppression is to be employed. Clear debris regularly
  • Establish exposure using the HSE HAVS calculator
  • Use suitable well-maintained equipment
  • Periodic monitoring of equipment Screening of operatives and regular monitoring Rotation of labor with adequate breaks from the use of the tool.
  • Ensure all equipment and cables are regularly maintained and tested
  • Only competent and trained operatives to use the tool. Changing of blades by trained personnel only. Blades are to be checked every time before use. Goggles are to be worn by the user when cutting.  Petrol-driven equipment is to be filled in a controlled manner in conjunction with a drip tray and spill kit. Do not leave the equipment running and unattended.
  • It can be caught from contact with urine, Therefore, all on-site are made aware that hygiene is essential as a means of avoiding the disease. Wash hands before eating and cover all open cuts in the best way to protect against Weil’s disease. Before work commences a Tool Box Talk will be delivered to all site operatives.
  • Physical protection of the apparatus is achieved by the placement of steel skip to completely cover the
  • apparatus. The soil was then heaped over the apparatus including the exposed horizontal pipe extending from the borehole
