May Safety Topics: 8 Toolbox Talks for the First Warm Weeks

May safety topics sit between spring and summer. Outdoor work is in full swing, the first properly warm days arrive, and several national campaigns compete for your attention. This plan picks the ones that matter most on site: electricity, falls, hearing, mental health and early heat.

Here are eight short toolbox talks, two a week, each with a full script in our toolbox talk topic library.

Why do these May safety topics fit the month?

Electricity and falls each get a campaign. ESFI runs National Electrical Safety Month every May to help reduce electrical fires, deaths, injuries and property loss. Start the month with electrical safety basics and power tools, where cords, plugs and chargers are part of everyday work.

OSHA's National Safety Stand-Down to Prevent Falls in Construction is also held in May. OSHA says falls from elevation continue to be a leading cause of death for construction workers: 389 of the 1,034 construction fatalities recorded in 2024. A stand-down is voluntary, and OSHA says workplaces without fall hazards can use it to discuss their other job hazards instead.

Noise and mental health share week 3. OSHA cites a CDC estimate that 22 million workers are exposed to potentially damaging noise at work each year. May is National Speech-Language-Hearing Month, which makes it a good time for the hearing protection talk. It's also Mental Health Month, which Mental Health America founded in 1949.

The first heat catches people out. OSHA's data on new workers is stark. Almost half of heat-related deaths happen on a worker's first day on the job or first day back after an extended absence. More than 70 percent happen during the first week. OSHA counts workers going through the seasonal change in spring and early summer as new to the heat, because their bodies haven't adjusted yet.

How should you run your May toolbox talks?

Keep each talk to about five minutes and use real equipment. In week 1, check cords and plugs together and take damaged ones out of service on the spot. In week 2, follow OSHA's stand-down format: stop work, talk about the fall hazards on this job, and let workers tell managers what they see.

For week 3, ask the crew to try OSHA's simple noise check: if you have to raise your voice to talk to someone 3 feet away, noise may be over 85 dBA. Then shift gears gently to mental health, and remind people where to find support.

Finish with the heat stress toolbox talk and hydration. Build a gradual start into the schedule for anyone new or returning, as OSHA recommends acclimatization. Our RPE scale gives crews a simple way to say how hard a task feels in the heat.

What seasonal tips go with your safety topics for May?

• Heat isn't only a summer problem. OSHA says hazardous heat can occur indoors or outdoors and in any season if the conditions are right.
• Know the risk factors. OSHA lists heavy physical activity, warm or hot conditions, lack of acclimatization and clothing that holds in heat.
• Hearing programs start at 85 dBA. OSHA requires a hearing conservation program when exposures reach 85 dBA as an 8-hour time-weighted average in general industry.
• Plan work at height. Before a new roof, ladder or scaffold job, write it up with our free JSA template.

Plan ahead for June

June is National Safety Month, opens with CPR and AED Awareness Week and closes with Lightning Safety Awareness Week. Keep the heat talk handy, because these May toolbox talk topics will matter even more as summer builds.
