What is a Boiler Suit?

A boiler suit is a one-piece protective garment designed for heavy-duty and hazardous environments. It offers full-body protection and is commonly used in marine, offshore, and industrial settings.

Key Features of Boiler Suits:

• Made from thick, durable fabric
• Resistant to oil, grease, and chemicals
• Provides high-level protection
• Designed for tough working conditions
• Often includes reflective strips for visibility

Common Uses:

• Ship engine rooms
• Offshore oil rigs
• Heavy industrial operations
• Dockyard maintenance

 Boiler suits are ideal when safety and durability are top priorities.

What is a Coverall?

A coverall is also a one-piece garment but is generally lighter and more comfortable than a boiler suit. It is designed for less hazardous environments where basic protection is sufficient.

Key Features of Coveralls:

• Lightweight and breathable fabric
• Comfortable for long working hours
• Easy to wear and remove
• Provides basic protection from dust and dirt

Common Uses:

• Manufacturing units
• Maintenance and repair work
• Workshops and light industrial jobs

Coveralls are best suited for tasks that do not involve extreme hazards.
