I read that as saying they couldn't stop her from wearing the hijab, which limits their options. Reading the article, it seems like the other deaths were caused by bad LOTO (lock out tag out) practices and one was some kind of traffic accident.
If it were me, I'd look at ways to avoid normalization of deviance. Maybe those with loose clothing can be given other things to wear or put into other roles. Factory jobs are inherently crappy and employers generally given you the legal minimums, as I know from direct experience. It's best to figure out ways to make complying with the rules easier so that most companies and most workers are complying with the law most of the time, but it's hard to give clear answers on how to do that. Hopefully things continue to improve. I'm sure there's a lot of room for it.
