The Many Trigger Height/Width of Fall Protection in Construction
For
friends and health and safety professionals benefit, who need quick access to
the standards of falls in construction, I made this guide. The first column are permitted measures, not
follow them, constitute a violation of the standards detailed in the third
column.
Para
beneficio de amistades y profesionales de seguridad y salud que requieren de un
acceso rápido a las normas de caídas de la construcción, preparé esta tabla. En
la primera columna están las medidas permitidas, que excederlas, constituyen
una violación a las normas detalladas en la tercera columna.
