Accidents in confined spaces – why do they happen?

A confined space is among the potentially most dangerous workplaces and confined space entry presents many challenges. Despite high safety precautions, too many accidents still happen worldwide, such as predominantly asphyxiation, exposure to hazardous substances or traumatic injuries to name just a few. Thus, when working in confined spaces, safety always comes first. Regarding the questions as to what causes an accident, there is more than one answer to that.

Frequent causes of accidents in confined spaces

  • Missing or insufficient hazard identification and risk assessment
  • Insufficient threat awareness
  • No selection or the incorrect selection of gas detection instruments
  • The use of unsuitable personal protective equipment or
  • The lack of training of workers who are designated for Confined Space Entry

How to avoid confined space accidents

The better a confined space entry is prepared the lower the risk. Here is a list of important questions that need to be answered in advance– before entering a confined space. 

  • Which legal regulations apply for this specific work assignment?
  • Are certified workers and proper devices available?
  • Does everyone know their responsibilities? 
  • Is the necessary operating instruction available?
  • Have your workers been trained regarding their individual activities? 
  • Have they been trained regarding the use of personal protective equipment?
  • Do you have an alarm and rescue plan for this specific mission? 
  • Have the recommended measures been consistently thought through?

Some companies are not even aware that their plants include confined spaces. This means that there is no risk assessment because a hazard has not been recognised. Information and consultation should be the first step. Once this has been addressed, there comes the confined space entry training. A proper training is an important prerequisite for avoiding accidents and to ensure the worker’s safety. Training sessions simulate a real work scenario and start, for example, by demonstrating the correct way to take clearance measurements and the use of personal protective equipment followed by entry and exit exercises.

Risk assessment

Risk assessment – manage hazards, risks and potential dangers

Risk or hazard – what’s the difference? What does a confined space risk assessment involve? A risk evaluation matrix helps you assess the challenges of confined space entry. Determine what confined space equipment is needed for the detection of any hazardous substances present and how to implement a safe system of work when working in confined spaces.

A matrix is a helpful instrument for risk assessment. It facilitates the systematic naming and evaluation of dangers and risks. Our example shows you how this might look.

Danger or risk: what is the difference?

When addressing workplace safety hazards it seems necessary to draw a distinction between “danger” and “risk”. 

“Dangers” are all aspects and framework conditions that could have a threatening influence on people, the environment, and plant safety with regard to a specific work situation. Such as entering a confined space. 

“Risks” are understood by workplace safety experts as the evaluation of the probability that this danger will occur in this exact situation and describes the specific potential of a hazard.

Hazardous substances may cause damages

  • Explosions: triggered by sparks, high temperatures or instable behaviour of substances
  • Bodily damage: contact with toxic gases, vapours, fluids or caustic substances
  • Long-term bodily damage: carcinogens or gamete-damaging effects of toxic substances
  • Uncontrolled reactions of chemical substances: contact with certain catalysts

Typical risks for workplace health and safety

  • Combustible gases and vapours
  • Toxic fluids and gases: like chlorine (Cl2), ammonia (NH3), hydrochloric acid (HCl)
  • Toxic organic substances: in particular benzene, methane, ethylene, butadiene
  • Particles: especially breathable ones
  • Additional dangers and risks: presented by specific work processes

A “safe system of work” – what does it mean for confined space entry?

The goal of the “safe system of work” is to minimise permanently the risks of specific work processes. This involves specifying methods and procedures that need to be implemented at a practical level when working in a confined space. Five partial steps to guide you to a safe system of work:

Step 1

Avoidance of risks via elimination of tasks

Step 2

Substitution by less dangerous or harmless processes

Step 3

Isolation of the danger via preventative interaction in the process (shut off mechanical functions, disconnect power supply, ventilation, etc.)

Step 4

Accompanying control measures (pre-entry measurement of toxic or explosive gases, of evaluation of entry options, etc.)

Step 5

Use of personal protective equipment (self-contained breathing apparatus, filter devices, chemical protection suits, etc.)

Confined space rescue – keep professionals equipped and briefed

A confined space rescue mission should only be carried out by trained professionals with first-hand experience to ensure confined space safety for all. A specific and well-established rescue plan should be in place for a confined space rescue. Technical equipment, as well as organisational and personalised measures, are the keys to success for potential escape and rescue situations.
