Disc cutter, a beard and a school run

Your gang is cutting out a failed reinstatement in a residential street outside a primary school. The work needs a petrol disc cutter for about 40 minutes, with a breaker to follow. The road is 30 mph with parked cars, and the 1.5 m pavement stays open. One operative has a full beard and is due to wear a tight-fitting half-mask respirator for the breaker work; another wears prescription glasses and says the goggles 'steam up so I don't bother'; a third is wearing a two-year-old hi-vis tabard that has faded to pale pink and has a torn pocket. The cutter's water suppression bowser is on the other van and will not arrive for an hour. School finishes at 15:00 and it is 14:20. The nearest cones are 30 m away, with pedestrians walking between them and the works.

1. What is your plan for the dust and silica exposure, given the water bowser is an hour away?

Read the worked answer

Do not start the cut dry, and do not treat the respirator as the control.

Respirable crystalline silica from dry cutting is the hazard, and the hierarchy is clear: suppress or extract the dust at source, then control the area, then protect the individual. A tight-fitting mask worn over a full beard cannot seal - facial hair in the sealing area makes the fit test meaningless and the assigned protection factor unachievable. That is a fact about the equipment, not a disciplinary matter: you cannot brief a beard away.

So:

  • Wait for the water bowser, or use on-tool extraction. If neither can be on site, the cut does not happen today - a 40-minute job is not worth a lifetime's silica exposure.
  • If a tight-fitting mask is genuinely needed for the breaker work, either the operative is clean-shaven in the seal area, or you move to a loose-fitting powered hood or air-fed head top, which does not rely on a face seal. Review the assessment to confirm the chosen RPE suits the task.
  • Face-fit testing and training must be current and recorded for whichever device is used.
  • Sequence the work around the school run. Cutting at 14:20 outside a primary school with the pavement open is the worst possible timing; starting at 15:15 after the children have gone reduces the number of people exposed and is a legitimate change to the programme.

The sequencing decision is a safety decision, not a convenience one.

2. How do you deal with the operative who has stopped wearing eye protection because it steams up?

Read the worked answer

Fix the PPE, not the person's attitude - but be clear that unprotected work stops.

Eye protection is required for disc cutting and breaking; the risk is flying fragments and, with the breaker, chips at eye level. 'It steams up' is a genuine failure of suitability, and the employer's duty is to provide PPE that is suitable for the wearer and the task, free of charge. Goggles that fog are not suitable.

Options to work through with the operative:

  • Prescription safety glasses to the right impact rating, which removes the 'over the glasses' problem entirely.
  • Overspec goggles designed to be worn over prescription frames, with anti-fog coating and adequate ventilation.
  • A face shield combined with the appropriate eye protection where the task warrants it.
  • Adjust the task - better technique, correct blade, water on the cut - which reduces the dust and debris causing the fogging.

The behavioural point: the operative should have reported the problem and been given an alternative, not quietly stopped wearing protection. Make it easy to report, and make clear that the task stops if the protection is not worn. Check the rest of the gang's PPE at the same time, because if one person has quietly dropped a control, others probably have too.

3. What do you do about the faded tabard, and what does the pedestrian situation tell you about the rest of the layout?

Read the worked answer

The tabard is not fit for purpose and gets replaced before the next task; the pedestrians tell you the layout is wrong.

The tabard. High-visibility clothing works through the retroreflective bands, which degrade with washing and UV. A tabard faded to pale pink has lost the fluorescent background that makes it conspicuous in daylight, and a torn pocket can snag. It no longer provides the standard the site requires. The employer must replace it free of charge, and the wearer must report damage or loss rather than keep wearing it. On a 30 mph street with parked cars restricting sight lines, the class of garment must match the assessment - a sleeved, banded garment is a better default than a tabard for work near moving traffic.

The pedestrians. Cones 30 m from the work, with people walking between the cones and the excavation, means the coning is defining something other than a safe works area. Ask:

  • Is the coned area actually enclosing the work and the plant?
  • Is there a defined pedestrian route with protection from the excavation and from the machine movements?
  • With school finishing in 40 minutes, will that route hold with a crowd of children and parents on it?

If the answer to any of these is no, the layout changes before the school run - including stopping the cut and closing the area if necessary.
