Risk Assessment: Construction and Civil Works
Workers Affected by Works Hazards
RISK
340 Vibrations.
RISK FACTORS
- Vibrations transmitted to the machine operator or driver (backhoe, dumper, cement mixer truck).
- Vibrations transmitted due to using machinery and tools (hammers, radial cutters/grinders, disc saws, vibrators, drills, etc.).
PREVENTIVE MEASURES
Rules for acting
- The points where tools are held are to have insulating material to avoid vibrations being directly transmitted to workers.
- Reducing exposure by:
- Limiting exposure time.
- Appropriate work scheduling.
- Information/training for workers exposed to the risk.
Personal protection
- Safety footwear.
- Safety goggles (depending on the type of vehicle) and whenever getting off the vehicle.
- Safety helmet (when getting off the vehicle).
- Safety belt.
- Anti-vibration belt.
- Wristbands.
- Thick gloves that insulate against vibrations.
RISK
370 Exposure to non-ionizing radiation.
Intoxication due to welding fumes.
RISK FACTORS
- Oxy-cutting and welding operations.
- Burns caused by an electric arc resulting from work with an electrical hazard: live work, work in the vicinity of live parts, cut-off or reconnection of the power supply, etc.
- Continued exposure to the sun.
- Presence in the surroundings of high voltage pylons (substations, etc.).
PREVENTIVE MEASURES
Rules for acting
- Maintain safety distances in the area in which this work is being carried out.
- Workers who are in the vicinity of these operations including welders’ assistants) are to be suitably protected, either with the pertinent PPE or by screening the area.
- To avoid the risk of burns resulting from jobs with an electrical hazard, all the precautions and procedures mentioned in the measures listed for preventing electric Contacts are to be applied.
- Adequately ventilate welding work.
- Use masks or breathing devices when necessary (both the welder and his assistant).
Personal protection
- Welding screens providing suitable protection.
- Jobs with an electrical hazard: those protections indicated for controlling the risk of electrical Contact.
- Protective screen against UV rays (cream).
- Possibility of using tinted safety goggles (sunscreen).
- Masks or breathing devices if necessary.
Procedures to apply
- P06 Aluminothermal welding work.
- P57 Work in confined spaces.
