Sure, moderate amounts of IR (nevermind the tiny amount from the smoke sensor) won't be a problem, but if someone puts high-intensity IR LEDs right up to their eyes I'm not so sure. Please edit your answer to include at least some caution. | |

| Mar 18, 2018 at 12:30 | comment | added | ThreePhaseEel | @dandavis -- the OP is referring to a photoelectric type smoke detector, not an ionization type | |
| Mar 18, 2018 at 12:29 | comment | added | dandavis | no, they are not safe, they contain radioactive materials you don't want a kid eating | |
| Mar 18, 2018 at 9:48 | comment | added | Janka | Smoke detectors either have 9V blocks or soldered lithium cells. | |
| Mar 18, 2018 at 6:10 | comment | added | Solar Mike | Unless they swallow the battery - not if it is a pp3 but a mercury button type cell... | |
| Mar 18, 2018 at 6:01 | comment | added | user39382 | The only danger I can think of would be if a child took out the battery and put it in their mouth. And even that isn't especially hazardous -- more of just a surprise. | |
