Toolbox Talk on PPE Safety: Ear and Nose Protection

Working in confined spaces is one of the most challenging and risky tasks on construction sites or industrial worksites. Tight areas like tanks, tunnels, pits, or ducts may hide silent hazards such as high noise, dust, fumes, and low oxygen levels.

Helmets protect your head and safety boots protect your feet from visible risks, but your ears and lungs are vulnerable to dangers you cannot see or always hear. Proper ear and respiratory protection are essential to ensure safety, alertness, and long-term health in confined spaces.

Toolbox Talk: Protect Your Ears, Nose and Lungs in Confined Spaces

Close Your Eyes and imagine that you are working inside a tunnel, tank, or pit. The air smells a bit dusty, the hum of machinery surrounds you, and you barely have room to move.

You’re focused on the task at hand, but your ears are ringing from the grinder, and your lungs feel tight from dust or fumes. In this environment, ear and respiratory PPE aren’t just optional—they’re your shield against invisible hazards that can silently damage your health.

Hearing Protection – What You Must Do

Confined spaces often amplify noise, and prolonged exposure can lead to permanent hearing loss or tinnitus.

DO’s:

Use earplugs or earmuffs rated for the specific noise levels. For environments above 85 dBA, choose earmuffs with a Noise Reduction Rating (NRR) of 25 dB or higher.
Select hearing protection suitable for your task:
Earplugs: Pre-molded or moldable, disposable or reusable, inserted into the ear canal.
Earmuffs: Sound-attenuating cups with soft cushions and a headband fitted over the ears.
Conduct fit testing to ensure proper attenuation. Individual fit-testing improves protection.

Don’ts:

Use earplugs in areas above 105 dBA without proper protection.
Rely on radio headsets or unapproved devices as hearing protection.
Modify your ear protection.
Wear earplugs if you have an ear infection; use earmuffs instead.
Insert earplugs with dirty hands to avoid infection.
Allow hair, clothing, or accessories to interfere with fit.
Remove hearing protection during noisy work.
Use stiff, worn, or damaged ear cushions or plugs.
Use earmuffs with stretched headbands that no longer seal properly.

Respiratory Protection – What You Must Do

Confined spaces may contain dust, fumes, chemicals, or gases. Proper respiratory protection is essential to prevent short- and long-term health issues.

DO’s:

Choose the right respirator for the hazard:
Air-Purifying Respirators (APRs) for low-risk environments.
Air-Supplying Respirators (ASRs) or Self-Contained Breathing Apparatus (SCBA) for IDLH (Immediately Dangerous to Life or Health) conditions.
Conduct annual fit-testing for respirators that rely on a face seal.
Inspect respirators before and after each use; replace filters and components as per guidelines.
Follow ventilation protocols and confined space safety procedures.
Attend training for correct respirator use and maintenance.

Don’ts:

Remove your respirator inside a hazardous confined space.
Use damaged masks or expired filters.
Ignore air quality warnings or safety protocols.
Let hair or loose clothing interfere with the respirator seal.

Why PPE Matters?

Noise: Long-term exposure can lead to permanent hearing loss.
Dust and fumes: Can cause chronic lung issues or short-term respiratory problems.
Ignoring PPE: Reduces alertness and increases the risk of accidents in confined spaces.
