Hazardous Energy
The three energies behind hazardous energy work
Pressure, electrical, mechanical
Small holes dug to expose and confirm a utility’s location
Test pits
This must be working, and is checked as a critical control before equipment moves
Backup alarm
The two energies behind toxic and flammable work
Chemical and thermal (fire)
Height above a lower level that triggers fall protection
6 feet
Excavation depth that requires a protective system
5 feet
The only crews allowed to enter confined spaces
Qualified pipe crews
No one works or walks under this
A suspended load
What STKY stands for
Stuff That Kills You
The two people who verify critical controls before STKY work starts
The Foreman or the Competent Person
Fitted on air hoses to stop them whipping if a fitting lets go
Whip checks
Two locating technologies listed as engineering controls
Ground-penetrating radar and electromagnetic locating
The site logistics plan separates people from equipment with these
Designated haul roads and walkways
Cutting method used to avoid hot work entirely
Cold cutting
Fall protection is required at all times, at any height, in this equipment
A boom-supported aerial lift
The required slope ratio, horizontal to vertical
1.5 to 1 (34 degrees)
B&S never enters this kind of space
A permit-required confined space
Approved document every critical lift must have
A lift plan
The most effective level of the hierarchy of controls
Elimination
System where the Pre-Start Check is recorded
Raken
Blocking or cribbing raised components is this type of control
Direct Control (Engineering)
Hand tools required when working around utilities
Non-conductive hand tools
Remote-controlled trench rollers are this level of the hierarchy
Substitution
Required during flammable liquid transfer to prevent static sparks
Bonding and grounding
The crew must know these plans before working at heights
The fall protection and rescue plan
An excavation under 5 feet still needs protection when these persons see any potential for cave-in
The Foreman or Competent Person
No one ever enters a space for this reason
To perform a rescue
The qualified person who directs the crane operator
The signal person
The three tests every energy control must pass
Timely, tangible, targeted
What happens if neither a Direct Control nor an Alternative Control System can be confirmed
The work shall not start
Clothing required where electrical work is involved
Arc-rated clothing (and electrical PPE)
Goal posts or flagging at overhead lines count as these two Alternative categories
Physical obstacle and visual reminder
A spotter is required in these two situations
When visibility is impaired or when working near other trades
Monitored during lime spreading
Wind
A personal fall arrest system only counts as Direct when these two conditions are met
Properly anchored, with fall clearance verified
Not permitted on B&S sites because all soil is treated as Type C
Benching
The two classifications that allow entry
Non-permit, or approved for alternate procedures
Governing policy for cranes and critical lifts
2.8 Cranes and Critical Lifts
Minimum makeup of an Alternative Control System
At least two controls from at least two different categories
First action when a Safety Absolute is violated
Stop the work and remove the person from the task
Name the two governing policies for hazardous energy
2.24 Control of Hazardous Energy and 2.28 Pneumatic and Hydrostatic Testing
Having the owner de-energize, deactivate, or relocate a conflicting utility is this level and type of control
Elimination (Direct)
Name the two governing policies for mobile equipment
2.16 Mobile Equipment and 2.17 Heavy Equipment Spotter
Name the three governing policies for toxic and flammable work
2.9 Hazard Communication, 2.12 Fire and Hot Work, 2.22 Silica
Name the two governing policies for working at heights
2.19 Fall Protection and 2.21 Stairways, Ladders and Scaffolds
The Competent Person inspects the excavation at these three times
Before each shift, after rain, and after any event that could change conditions
Rescue coordination with the fire department or a rescue company is required for these two entry types
Alternate procedures entries, and horizontal entries without a retrieval method
The three things a critical lift needs before it proceeds
An approved lift plan, a qualified rigger, and a qualified signal person
The three Alternative Control System categories
Physical obstacle, dedicated monitoring, visual reminder
The two outcomes the violation review decides between
Willful violation or system failure
