Confined Space Entry

Confined space entry refers to work performed in enclosed or partially enclosed areas where risks such as limited ventilation, toxic gases, or restricted access can endanger workers. Examples include tanks, vessels, and pipelines.

Where is confined space entry needed?

This is a common requirement in:

• Oil & Gas – offshore risers, flare booms, topside piping.
• Petrochemical & Chemical plants – process vessels, reactors, insulated pipelines.
• Marine & Offshore wind – deck areas, turbine towers, hull details.
• Infrastructure & Power – bridges, cranes, boilers, turbines.

For you as an operator, confined space entry is one of the highest-risk activities in maintenance, requiring strict HSE protocols and ATEX compliance.

Extra explanation and risks

Risks of confined space entry include:

• Toxic or explosive gases requiring gas detection and ventilation.
• Oxygen deficiency leading to suffocation.
• Restricted movement increasing accident risk.
• Emergency evacuation difficulties.

Regulations:

• OSHA 29 CFR 1910.146 (USA).
• EU Directives & National HSE laws.
• ATEX guidelines for explosive atmospheres.

Pinovo and confined space blasting

Pinovo makes confined space blasting safer by:

• PiHab™ enclosure – dust-free blasting in tanks or towers.
• ATEX-certified equipment – safe in explosive atmospheres.
• Dust and debris capture – prevents contamination and improves visibility.
• Less need for scaffolding – rope access possible with enclosure.

Pinovo does not remove confined space entry risks entirely, but greatly reduces dust, contamination and explosion hazards.
