Today there is a big debate about photoelectric and ionization smoke alarms. It's clear from the research that both have pros and cons, but some people today discount the ionization technology as being useless or even dangerous. I believe photoelectric is the better choice, but every smoke alarm we installed was ionization, and a big percentage of that 30 percent fatality decrease was because of all the smoke alarms we installed.so the role of fire prevention equipment is very important for making your organization safety.
