1 Persons at (Groups) Assessor Appointment Tel. No. Description of Task or Activity A One Direct employees Mark Bloxidge H&S Manager Working at height from Mobile Tower B Contractors/Sub contractors Scaffold C Tenants D Members of the public Work Type Review Date Routine July 2019 Hazard/ Severity Probability Existing Additional Required 1) Injury following the incorrect operation and use of a mobile tower scaffold A,B,C,D S P H 1) All scaffolding is to be erected, dismantled and altered in accordance the manufacturer s erection guide for system scaffolds. Towers will be erected following a safe method of work, either using: the advanced guard rail system or through the trap (3t) system M 1) Any operative erecting a mobile scaffold tower must be trained and competent to do so, all personnel working off a tower must be trained and competent to work at height. L Falls from height/ crush injuries/ contact electricity/ falling objects 2) Any proposed modifications or alterations outside a generally recognised standard configuration must be designed or approved in advance by a competent person. 2) When towers are used in public places, extra precautions are required: erect barriers at ground level to prevent people from walking into the tower or work area; Page 1

2 Hazard/ Severity Probability Existing Additional Required 3) To prevent use by unauthorised persons of complete or incomplete scaffolds, relevant warning signs identifying the areas where access is not permitted should be displayed at the access points to these areas. In addition, access should be prevented by suitable physical means 4) All towers must be inspected following assembly and then at suitable regular intervals by a competent person. In addition, if the tower is used for construction work and a person could fall 2 metres or more from the working platform, then it must be inspected following assembly and then every 7 days. 5) Towers rely on all parts being in place to provide adequate strength. The manufacturer, supplier or hirer has a duty to provide an instruction manual explaining the erection sequence, including any bracing. minimise the storage of materials and equipment on the working platform; remove or securely board-over access ladders to prevent unauthorised access if it is to remain in position unattended 3) Stop work if the inspection shows it is not safe to continue, and put right any faults. The result of an inspection should be recorded and kept until the next inspection is recorded. These instructions are to be followed. Always install stabilisers or outriggers when advised to do so in the instruction manual. Page 2

3 Hazard/ Severity Probability Existing Additional Required 6) When moving a tower you should always: reduce the height to a maximum of 4m; temporarily raise outriggers; check that there are no power lines or other obstructions overhead; check that the ground is firm, level and free from potholes and obstacles; and push or pull using manual effort from the base only. Never move a tower while people or materials are on the tower, or in windy conditions. 7) Prior to use check for damage, excessive wear, distortion, oxidation and corrosion. Scaffold must be free from oil, mud, cement (slip hazards and corrosion). Lockable castors must be in good condition and braked 6) Any defects noted should be immediately reported and monitored to completion, or equipment should be removed from use 10) Work to be suspended in the event of inclement weather such as heavy rain, high winds, frost or snow (until adequate grit can be applied) and lightning 8) Do not use steps on uneven, slippery, sloping or soft ground. The ground may have to be levelled and compacted in advance. Page 3

4 Hazard/ Severity Probability Existing Additional Required 9) To maintain tower stability you must make sure: the tower is resting on firm, level ground the locked castors or base plates properly supported. Never use bricks or building blocks to take the weight of any part of the tower; stabilisers or outriggers are installed when required and always follow the instruction manual; and that a tower is never erected to a height above that recommended by the manufacturer. 10) Exclude other vehicles, mobile plant/work equipment from the works vicinity for the duration of the work. 11) Operatives to monitor weather conditions 12) Do not exceed the specified loading rating of the scaffold. Add workers weights, plus their tools plus the weight of materials to calculate safe tower loading. 13) Do not carry out work operations in poorly lit areas. Page 4

5 Hazard/ Severity Probability Existing Additional Required 14) Be particularly mindful of the sail effect which large work materials can produce e.g. plywood, glazing. This sail effect can be extremely hazardous even in light winds blowing material off towers. 12) Additional task lighting to be supplied 15) Wear appropriate Personal Protective Equipment (PPE) as identified, safety footwear, gloves 16) Do not over-reach. Work only in safe reaching distance. Page 5

7 Contingency Plan Item No Hazard/ Occurrence Contingency/Action 1 Unauthorised entry to working area. Violence and aggression / public access to restricted work area 2 Electricity failure / flood / pipe leak / striking cable / pipework Lighting failure / water in premises / electrocution 1) Aggressive behaviour / damage to access equipment 1) Work would cease. Unauthorised visitors asked to leave One Direct supervisor informed. Emergency services called if required. 2) Lone working procedure in place. 1) Severance of services / lighting failure. 1) Work would cease and client would be informed by One Direct Supervisor so remedial work can be carried out in order for the work to re-start. 3 Poor communication / lack of contact between direct labour and subcontractors Poor standards / work being carried out in an inappropriate manner 1) Poor standard of work / low customer satisfaction / violent and aggressive behaviour from customer 1) One Direct supervisor to keep all parties informed of work procedures and standards, H&S inspections to take place. 4 Disturbance of asbestos containing materials Exposure to asbestos related illness 1) Lack of appropriate asbestos information supplied for the property / task 2) Failure to comply asbestos procedures 1) Implement emergency asbestos procedure.
