Permit-Required 

Confined Spaces

A confined space has limited openings for

entry or exit, is large enough for entering and 

working, and is not designed for continuous 

worker occupancy.  Confined spaces include 

underground reservoirs, ground storage tanks, 

elevated tanks, silos, manholes, and pipelines.

Confined Space Tips

 

 Do not enter permit-required confined spaces 

  without being trained and without having a

  permit to enter. 

 Review, understand and follow employer’s

  procedures before entering permit-required

  confined spaces and know how and when

  to exit. 

 Before entry, identify any physical hazards. 

 Before and during entry, test and monitor for 

  oxygen content, flammability, toxicity or

  explosive hazards as necessary. 

 Use fall protection, rescue, air monitoring, 

  ventilation, lighting and communication 

  equipment according to entry procedures. 

 Maintain contact at all times with a trained 

  attendant either visually, via phone, or by

  two-way radio.  This monitoring system

  enables the attendant and entry supervisor

  to order you to evacuate and to alert

  appropriately trained rescue personnel to

  rescue entrants when needed. 
Refer to 29 CFR 1910.146 for complete 

regulations set by OSHA.  Refer to your state's 

regulations if your state established and operates 

their own safety and health programs approved 

by OSHA.

Protect Yourself 

It is important that you comply with all relative 

OSHA and local regulations while installing 

and performing any maintenance to the mixer 

circulation equipment.  
Key OSHA Compliance Standards that must

be followed (and not limited to) are:

• 

1910.146 Permit-required confined spaces

• 

1910.147 Lockout/Tagout

• 

1926.500 Fall Protection

Fall Protection Tips

 

 Identify all potential tripping and fall hazards 

  before work starts. 

 Look for fall hazards such as unprotected

  floor openings/edges, shafts, open hatches,

  stairwells, and roof openings/edges. 

 Inspect fall protection and rescue equipment

  for defects before use. 

 Select, wear, and use fall protection and

  rescue equipment appropriate for the task. 

 Secure and stabilize all ladders before

  climbing. 

 Never stand on the top rung/step of a ladder. 

 Use handrails when you go up or down stairs. 

 Practice good housekeeping. Keep cords, 

  welding leads and air hoses out of walkways

  or adjacent work areas.
Refer to 29 CFR 1926.500 for complete 

regulations set by OSHA.  Refer to your state's 

regulations if your state established and operates 

their own safety and health programs approved by 

OSHA.

Lockout Tagout

When the On/Off switch is in the "ON" position, 

the mixer may start up at any time if not already 

operating.  The mixer's On/Off switch can be 

locked out by placing a pad lock thru the door latch 

of the controller after the switch has been turned 

to the "OFF" position.  The On/Off switch is to be 

used as the emergency stop.
