RISK ASSESSMENT

  • Why do it?
  • In most countries, the use of specific materials or the operation of specific facilities is not allowed unless it can be shown that they do not increase the risk of death or illness above a certain threshold ………………. Legislation!

RISK ASSESSMENT

Why do it?

  • Health & Safety at Work Act 1974
  • Management of Health & Safety at Work Regulations 1992 (1999)
  • Ionising Radiations Regulations 1999

University of Glasgow Radiation Protection Service

health safety at work act 1974
HEALTH & SAFETY AT WORK ACT 1974
  • “It shall be the duty of every employer to ensure, so far as is reasonably practical, the health, safety and welfare at work of all its employees.”
  • “It shall be the duty…..persons not in his employment who may be affected thereby are not thereby exposed to risks to their health and safety.”

University of Glasgow Radiation Protection Service

management of health safety at work regulations
MANAGEMENT OF HEALTH & SAFETY AT WORK REGULATIONS
  • Every employer shall make a suitable and sufficient assessment of:
    • risks to health and safety of employees at work
    • risks to health and safety of persons not in his employment arising out of his undertaking

University of Glasgow Radiation Protection Service

ionising radiations regulations 1999
IONISING RADIATIONS REGULATIONS 1999
  • “An employer shall not carry on work with ionising radiation unless he has made an assessment of the radiation hazard to employees or other persons …. in the event of any reasonably foreseeable accident, occurrence or incident.”

University of Glasgow Radiation Protection Service

ionising radiations regulations 19991
IONISING RADIATIONS REGULATIONS 1999
  • “Before a radiation employer commences a new activity, in respect of which no risk assessment has been made by him, he shall make a suitable and sufficient assessment of the risk to any employee and other person…..”
  • “All hazards which could cause a radiation accident to be identified and evaluated.”

University of Glasgow Radiation Protection Service

summary
SUMMARY

Why do it?

  • Employers are legally required to have done a risk assessment
    • suitable and sufficient
    • identify measures needed to restrict exposure
    • identify and quantify potential radiation accidents

RISK ASSESSMENT

Why do it? – Good Practice

A Good Risk Assessment Can -

  • Identify steps to prevent radiation accidents occurring
  • Limit the effects of radiation accidents
  • Prepare employees for coping with radiation accidents
  • Draw up contingency plans

The five steps!

University of Glasgow Radiation Protection Service

step one
STEP ONE
  • Hazard identification
  • Determine the nature of the potential adverse consequences of using radiation
  • Use the literature!
  • Don’t forget other hazards associated with the experiment or procedure.

University of Glasgow Radiation Protection Service

step two
STEP TWO
  • Decide who might be harmed and how
  • Don’t forget ….
  • Young persons, trainees, new or expectant mothers, cleaners, visitors, contractors, maintenance workers, members of the public, people who share your workplace….

step three
STEP THREE
  • Evaluate the risk
  • Deterministic - dose threshold
  • Stochastic - ALARP
  • Exposure assessment - decide how likely it is to cause harm
  • Risk control – decide on suitable measures
  • Even with precautions, is remaining risk high, medium or low?

University of Glasgow Radiation Protection Service

step three continued
STEP THREE CONTINUED
  • Are all things required in law done? Don’t stop there - is the remaining risk small? If not, how to make it small?
  • Think about other possible occurrences - moving sources within the site, new staff, risk of lost sources, human factors.

step four
STEP FOUR
  • Record your findings
    • Only a legal requirement if five or more employees
    • Minimum record to include
    • Date, hazard e.g. isotope, activity (MBq)
    • External / internal, contamination, spills, personal contamination, waste disposal, lost material etc
    • Personnel at risk - names
    • Special Risks (eg 1 team member pregnant, need to work between two laboratories, control measures)

University of Glasgow Radiation Protection Service

step four continued
STEP FOUR CONTINUED
  • Other risks – e.g. toxic chemical
  • Assessment must be signed by author
  • Assessment must be reviewed by RPS / RPA

University of Glasgow Radiation Protection Service

step five
STEP FIVE
  • Review your assessment and revise it if necessary
  • Changes leading to new hazards
  • Periodic review to make sure still fit for purpose

Risk Control

  • Physical, engineering or administrative controls?
  • Protective equipment needed (e.g. safety glasses, gloves etc)
  • Need for training?
  • Procedures to follow (e.g. monitor area before/after use)
  • Specific area set out – e.g. Controlled Radiation Area?
  • next
