▶ Calculator App URL: https://lp.wssl.co.jp/dentaku_app/ ■ Development Background "We want to reduce fire accidents caused by hazardous materials worldwide." For companies handling hazardous materials in manufacturing, logistics, and construction sites, accurately grasping "how many times the designated quantity" their stored hazardous materials amount to is essential for compliance with fire service laws. However, in practice, many cases involve manual calculations while referring to different designated quantity values for each item, placing a burden on site personnel due to calculation errors and the complexity of confirmation work. Especially when storing multiple items mixed together, calculating the sum of multiples is difficult to do accurately without specialized knowledge, and it often takes a long time to make decisions for notifications and permit procedures to the fire department. Proper management leads to reliable safety.
