PASMA Environmental Considerations 3

Question 1

What precautions are needed when using a tower scaffold in an area with dust or airborne particles?

Accepted Answer

RPE (respiratory protective equipment) may be needed, and dust can reduce visibility, create slip hazards on platforms, and affect component mechanisms

Answer

Airborne dust or particles may require RPE (masks or respirators), eye protection, and additional cleaning of platforms. Dust accumulation on platforms creates slip hazards, and fine particles can interfere with locking mechanisms on components.

Question 2

What is the risk of using a tower scaffold near chemical storage or processing areas?

Accepted Answer

Fumes may be toxic requiring RPE, chemical spills may corrode components, and some chemicals are flammable creating fire and explosion risks

Answer

Chemical environments introduce risks of toxic fume inhalation, corrosive damage to aluminium components, fire and explosion hazards, and contamination of workers. A COSHH assessment must identify the chemicals present and the necessary controls.

Question 3

How does altitude (above sea level) affect tower scaffold use?

Accepted Answer

Higher altitudes generally mean higher wind speeds, lower temperatures, and reduced air pressure, all of which affect worker performance and tower stability

Answer

At higher altitudes (e.g., mountainous terrain), wind speeds tend to be higher, temperatures lower, and the reduced air density can affect breathing during physical exertion. These factors must be considered in the risk assessment for elevated work sites.

Question 4

What lighting considerations apply when using a tower scaffold?

Accepted Answer

Adequate lighting must be provided for safe access, working, and inspection — natural or artificial, without creating glare or deep shadows

Answer

Under the Workplace (Health, Safety and Welfare) Regulations 1992, adequate lighting must be provided. At height, poor lighting increases the risk of trips, misjudged steps, and unidentified hazards. Light sources must not create glare or deep shadows that obscure hazards.

Question 5

What is the risk of noise exposure when working on a tower scaffold?

Accepted Answer

Loud noise from nearby machinery or operations can prevent operatives from hearing warnings, communicating, and can cause distraction leading to falls

Answer

Excessive noise impairs communication between the platform and ground level, prevents operatives from hearing warning signals or approaching vehicles, and can be distracting. Under the Control of Noise at Work Regulations 2005, noise exposure must be assessed and controlled.
