English to Spanish Tech/Engineering Safety

"This would provide a better work quality for the operators who had to continuously carry escape hoods due to safety regulations."
"Escape hoods were a subset of gas masks that were designed to protect individuals in the event of an emergency."

Según una imagen que aparece, se trata de unas "mascarillas" para protegerse en caso de fugas, etc. ¿Existe un término más preciso para estas "escape hoods"?

Gracias,
