Falling on chest?: Seriously, propane or other combustion in an enclosed space can cause carbon monoxide buildup and death. Electric is thought to dry the air ; annoy nasal passages/upper airways. Practically speaking, all are ok as long as used properly, may consider moisturizing air if dry ; be sure ventilated if small / tight space.
