Open toed shoes, shorts, not wearing goggles. In the lab, you work with many different chemicals, and with open shoes, shorts and no goggles you face the risk of burning feet, legs and eyes with all sorts of volatile, oxidative and combustible chemicals.
If its cutting out it could be the fuel pump. They usually would make your car cutout on hills.
Long un-tied back hair: could potentially fall, move into chemicals on bench, bunsen burner flame etc Exposed footware (FlipFlops etc): If chemicals spill onto floor, would burn straight onto skin with no protection. Broken glassware also hazard. Lack of long trousers: Again to protect against chemical spills onto bare legs. Lab coats, goggles, optional gloves depending on what is happening, are all good safety wear.
