The point
Two things out here can hurt you. The heat can drop you today. The sun can catch up with you in twenty years. Both are easy to shrug off, and both are easy to deal with. Five minutes on it now, then we crack on.
The hazard, in plain terms
When you graft in the heat, your body works hard to keep itself cool. On a hot day, under kit, it can start to lose that fight. First you can't concentrate. Then come muscle cramps, maybe a heat rash. Feeling dizzy, sick, headachey, skin clammy - that's heat exhaustion. If a mate goes hot and dry, confused, talking rubbish - that's heat stroke, and that's an ambulance job. And here's the catch: by the time you're gasping for a drink, you're already behind. Thirst turns up late.
The sun is the slow one. If your skin goes even a bit red, it's damaged. Burn and peel enough summers and it ages the skin, and it raises your chance of skin cancer. Fair or freckled skin, red or fair hair, lots of moles - you're first in line. But nobody is off the hook. Every skin type can overheat and dry out.
What to do
- Drink water little and often, all day. Don't wait until you're thirsty.
- Take your breaks in the shade - especially at lunch.
- Pace the heavy work. Where the job allows, do the hardest graft in the cooler parts of the day.
- Keep your top on, and wear a hat that covers your ears and the back of your neck.
- Put sunscreen, factor 30 or higher, on any skin still showing.
- Watch each other. If a mate looks wobbly, confused or clammy, get them into the shade, get water into them, and tell me straight away.
What to never do
- Never strip off to get a tan. Red skin is damaged skin, every time.
- Never push through dizziness or cramps. That's your body losing the fight, not you winning it.
- Never ignore a mole or spot that's changing shape, size or colour, or that itches or bleeds. See a doctor, promptly.
Questions to ask the crowd
The talk ends in a conversation. These are the ones that start it.
- Where's the nearest drinking water and the nearest shade on this site, right now?
- What would you actually do if the person next to you went confused and hot to the touch?
- Who's had a proper look at their own skin this year, and what would send you to the doctor about it?
A toolbox talk is a refresher and a conversation. It is not formal training, and it does not by itself make you or your site compliant.
