Legal requirement of MHSWR 1999

• Reg 3 - Suitable and sufficient assessment of
  the risks presented by work activities
• Reg 36 - Significant findings recorded where
  there are five or more employees
• Reg 5 - recording of the arrangements for
  planning, organisation, control, monitoring and
  review of the preventive and protective measures

Definitions

• Hazard - Something with the potential to cause
  harm
• Substances or machines
• Methods of work
• Other aspects of work organisation
• Harm - physical injury or ill-health suffered by
  those exposed to the hazard.
• Risk -Likelihood that the harm from a particular
  hazard is realised

7
General principles of risk management

• Avoid the risks
• Evaluate the risks that cannot be avoided
• Combat risks at source
• Adapt the work to the individual
• Adapting to technical progress

8
General principles continued

• Replacing the dangerous by the non-dangerous or
  less dangerous
• Develop a coherent overall prevention strategy
• Give collective protective measures priority
• Give appropriate instruction to employees

9
Responsibility

• Process is initiated by the agent
• Competent staff delegated to prepare risk
  assessments
• Each risk assessment must be approved and signed
  by the agent
• The agent is responsible for ensuring that risk
  assessments are regularly reviewed
• Author briefs workforce on content

10
Five steps to risk assessment

• 1 - Look for the hazard
• 2 - Decide who might be harmed and how
• 3 - Evaluate the risk and decide whether
  existing precautions are adequate
• 4 - Record the findings
• 5 - Review the assessment and revise if necessary

11
1 - Look for the hazard

• Excavation work hazards
• Collapse of excavation
• Oxygen deficiency
• Toxic or flammable gas
• Underground services gas, electricity or water
• Falling materials or plant
• Falls of persons
• Ingress of water
• Weakening of adjacent structures
• Noise
• Biological e.g. leptospirosis

12
2 - Decide who might be harmed and how

• Who
• Operatives involved in operation
• Maintenance cleaning workers
• Contractors
• Visitors to workplace
• Passers-by and members of the public

• How excavation
• Crush injury
• Asphyxiation
• Burns due to fire or explosion
• Electrocution
• Drowning

13
3 - Evaluate the risk

• Severity of injury
• High - death, serious injury/damage to health
• Medium - injury/damage to health requiring time
  off work
• Low - minor injury/damage to health
• Likelihood of hazard being realised
• High - very likely
• Medium - possible
• Low - unlikely
• Risk rating - Severity x Likelihood H x M H

14
3 - Decide whether existing precautions are
adequate

• If inadequate apply control measures to reduce
  the residual risk to an acceptable level
• Use past experience, brainstorming, SG01
• Implement new / additional controls measures
  following the hazard and risk control strategy
• Safe place
• Safe person

15
Hazard risk control strategy / hierarchy

• Prevention
• Eliminate
• Reduce
• Isolation
• Control
• Controls
• Personal protective equipment
• Discipline

16
Some control measures for excavations

• Consider methods of work that do not require
  entry
• Support materials on site before excavation
  starts
• If there is a possibility of underground services
  being present, the area surveyed using a suitable
  detection instrument
• If there could be ventilation problems, a gas
  monitor used to monitor atmosphere before entry,
  air movers used to increase ventilation
• Plant and materials kept away from the side of
  excavations to prevent undue pressure of ingress
  of exhaust fumes
• Excavations suitably illuminated
• Edge protection installed to prevent falls into
  excavation

17
4 - Record the findings
18
5 - Review the assessment and revise if necessary

• Review following
• Accident
• Complaint
• Change in system, plant or material of the
  particular activity
• Change of legislation
• New information from manufacturer
• Publication of new guidance
