Matsuyama, Ehime security firm shields guards with layered heatstroke measures

Security guards for Matsuyama's SHINWA company work about seven hours in scorching sun, prompting the firm to implement layered heatstroke prevention measures to protect workers' health. Measures include salt tablets, frozen drinks (about 40 bottles daily), cooling vests paired with fan-equipped wear, daily heat-index alerts via social media, and health-recording sheets. Nationally, 1,803 workplace heatstroke casualties occurred last year, including 199 security workers. Guards consume up to 10 bottles on peak days, rest in air-conditioned vehicles, and can be quickly relieved if unwell. The company says investing in prevention is essential since workers cannot do their jobs without health.
