Staying Safe in Confined Spaces: What Every Employer Needs to Know

Confined spaces are some of the most underestimated hazards in the workplace. Tanks, silos, pits, sewers, service ducts, and even poorly ventilated plant rooms can all qualify as confined spaces. They may look harmless, but the risks inside can escalate rapidly, turning routine tasks into life-threatening emergencies.

Why Confined Spaces Are So Dangerous

Confined spaces present unique hazards: lack of oxygen, toxic or flammable gases, flooding or engulfment, entrapment, and restricted access for rescue. Workers can become incapacitated within seconds when exposed to dangerous atmospheres. Even well-trained rescuers can be at risk if they enter without proper planning.

The Legal Duty for Employers

Under the UK Confined Spaces Regulations 1997, employers must take all reasonable steps to identify, assess and control the risks associated with confined spaces. This includes avoiding entry wherever possible, implementing safe systems of work, and ensuring employees are trained and equipped for the tasks they carry out. Despite clear rules, incidents still happen every year because hazards are underestimated, risk assessments are incomplete, or procedures are not followed.

Core Elements of Confined Space Safety

Base Solutions’ Working in Confined Spaces online course equips workers and supervisors with the knowledge to handle confined space work safely. It covers:

• Identifying confined spaces and potential hazards – recognising high-risk areas before work begins.

• Atmospheric testing and ventilation – using monitoring equipment and ventilation to maintain safe conditions.

• Safe systems of work including permits and supervision – why a permit-to-work system is critical.

• Emergency procedures and rescue planning – preparing for worst-case scenarios so no one is caught off guard.

Benefits of Proper Training

Investing in training creates a safety culture where staff understand the “why” behind procedures. It also:

• Protects your workforce from potentially fatal accidents.

• Reduces the risk of legal action or costly downtime.

• Demonstrates compliance with UK health and safety law.

• Builds confidence among employees and contractors working in or around confined spaces.
