Product Overview

This risk assessment covers the selection, setup, use and maintenance of atmospheric monitoring and gas detection equipment. It supports the identification and management of changing atmospheric conditions, equipment limitations, access controls and emergency actions.

Activities & Risks Covered

This assessment addresses activities and risks including:

  • Plan monitoring work and assess the area
  • Control access and isolate the monitoring area
  • Inspect gas detection equipment for readiness
  • Transport, handle and set up monitors and gas cylinders
  • Conduct initial atmospheric testing
  • Monitor atmospheric conditions throughout the work
  • Use ventilation and atmospheric controls
  • Respond to alarms, evacuation and emergency situations
  • Coordinate worker competency, supervision and communication
  • Review work, maintain equipment and keep records

Who is this for?

Suitable for contractors, workers, supervisors and businesses carrying out atmospheric monitoring and gas detection activities.

Activities & Hazards Covered

Activity Potential Hazards
Planning and work area assessment
  • Wrong monitor selected for the atmosphere or process hazards present
  • Hazards not identified from previous contents, adjacent processes or low-lying areas
  • Workers entering or approaching an area before the need for atmospheric monitoring is confirmed
  • Unclear emergency arrangements or communication methods
Access control and isolation of the monitoring area
  • Unauthorised entry into an area with unknown or unsafe atmosphere
  • Atmosphere affected by adjacent plant, vehicle exhaust, product transfer or process upsets
  • Ignition sources introduced into potentially flammable areas
  • Unexpected energisation or movement of nearby plant creating additional atmospheric or physical hazards
Inspection and readiness of gas detection equipment
  • Faulty, damaged or unsuitable detector giving false readings
  • Flat battery, blocked sensors or failed alarms
  • Using equipment outside calibration period or without functional checks
  • Incorrect detector configuration for the gases likely to be present
Transport, handling and setup of monitoring equipment and gas cylinders
  • Manual handling strains while carrying monitors, pumps, tripods, hoses or calibration gas
  • Cylinder leak, impact or uncontrolled movement
  • Trip hazards from hoses, leads and sampling lines
  • Equipment damage during transport leading to unreliable readings
Initial atmospheric testing
  • Exposure to oxygen-deficient, oxygen-enriched, toxic or flammable atmosphere during testing
  • Testing from the wrong location or only at one level, missing gas layering
  • Using smell or other senses instead of instrument readings
  • Worker moving too close to a suspect atmosphere while taking samples
Ongoing monitoring during the work
  • Atmosphere changing after initial test due to process release, sludge disturbance, ventilation failure or nearby work
  • Workers becoming complacent after one acceptable reading
  • Loss of monitor visibility or audibility in noisy or restricted areas
  • Exposure developing between periodic checks
Ventilation and atmospheric control
  • Contaminants not dispersed, causing poisoning, asphyxiation or flammable atmosphere
  • Ventilation introducing contaminated air or spreading vapours to other workers
  • Oxygen enrichment or displacement from purging gases
  • Restart of work before the atmosphere is restored to a safe level
Alarm response, evacuation and emergency actions
  • Delayed evacuation after gas alarm or unsafe reading
  • Workers re-entering before the atmosphere is reassessed
  • Panic, poor communication or attempted rescue without proper controls
  • Serious injury or fatality from toxic exposure, fire or oxygen-deficient atmosphere
Worker competency, supervision and communication
  • Inexperienced workers misreading instruments or misunderstanding alarms
  • Poor handover of current readings, hazards or changed conditions
  • Contractors or visitors entering without understanding restrictions
  • Insufficient supervision for higher-risk monitoring activities
Post-work review, equipment maintenance and record keeping
  • Defective equipment returned to service
  • Missed trends from repeated alarms, near misses or abnormal readings
  • Loss of monitoring records needed for follow-up controls
  • Residual contamination on equipment or stored cylinders
