Provide a shutoff valve.

You must provide each steam and airlift hammer with a quick-closing emergency valve in the admission pipeline that is distinctly marked and in a convenient location. This valve needs to be closed and locked in the "off" position when the hammer is being adjusted, repaired, or serviced, or the dies are being changed.
For requirements about Lockout/tagout (control of hazardous energy), see chapter 296-803 WAC.
