Working at Heights
The primary energy source behind falls
Gravity
All soil on B&S sites is treated as this soil type
Type C
The two energies behind confined space hazards
Chemical (atmosphere) and gravity (engulfment)
Lines used to control a load’s swing
Tag lines
The primary energy in a work zone
Motion (public and site traffic)
Each worker puts one of these on the isolation point
Their own lock and tag
No mechanized excavation without a valid one of these
One-call (811) ticket
Only these people may operate mobile equipment
Authorized operators
This document must be accessible at the work area
SDS (Safety Data Sheet)
Minimum PPE on every site: hard hat, safety glasses, gloves, safety-toe boots, and this
High-visibility outer layer
Rated for 5,000 lb or designed by a Qualified Person
A fall protection anchor
Minimum distance spoil piles are kept from the edge
5 feet
System where confined space evaluations and alternate procedures permits are recorded
Raken
Outriggers must sit on these
Mats or cribbing
Flaggers in a work zone must be this
Certified
No one works on a system until energy is verified at this level
Zero energy
Besides the ticket, these must be verified before digging
Utility marks
Must be worn whenever equipment is moving
Seat belt
Training the user must complete before using a hazardous chemical
HazCom/GHS
Meeting where the Daily Job Brief is discussed
Morning Huddle
Guardrail systems and rated, labeled hole covers are this type of control
Direct Controls (Engineering)
A ladder or ramp must be within this lateral distance in excavations 4 ft or deeper
25 feet
Required retrieval setup for vertical entries
Tripod and winch
Use this instead of an excavator when it has no manufacturer lift chart
A crane
Minimum ANSI/ISEA 107 high-visibility class on B&S sites
Class 2
You must never enter this area around a line under test
The pressure test exclusion zone
The two ways a utility in the tolerance zone must be exposed
Hand digging or vacuum excavation
What you need before entering the swing radius or travel path
Eye contact with the operator and acknowledgment
Flammable liquids are stored and dispensed only in these
Approved, labeled safety containers
Every crew member must review and do this to the AHA before work
Sign it
Warning lines and a safety monitor together are this type of system
Alternative Control System
Depth beyond which a registered PE must design the protective system
20 feet
Weather condition that means no entry
Rain or a rain forecast
The barricaded area under and around the load is this kind of Alternative control
Physical obstacle
Portable concrete barrier or a truck-mounted attenuator
Positive protection (Direct Control)
Preferred over pneumatic testing because compressed air stores more energy
Hydrostatic testing
Policy that sets overhead line clearance distances
2.31 Utility Avoidance and Underground Utilities
ROPS with seat belts is this type of control
Direct Control
Who can look up HazCom/GHS training records
All management team members on employees Raken profile under certifications.
Besides the site, this document prescribes required PPE
The AHA and SDS
Name the three critical controls verified before work at heights starts
Guardrail/cover in place or PFAS anchored with fall clearance verified; rescue plan known to the crew; fall protection equipment inspected
The only three acceptable cave-in protections
Sloping (1.5:1), trench box/shield, or shoring
The two people who must be in place at the point of entry and outside the space
Entry Supervisor and attendant
Name the five critical controls before a lift
Lift plan complete; rigging inspected and rated; exclusion zone barricaded; signal person assigned; ground conditions verified
The traffic control plan must follow this federal manual, Part 6
MUTCD
The four steps before working on or inside a system
Isolate, lock, tag, verify zero energy
Assigned when equipment works near the overhead clearance distance
A spotter
Inspection required before equipment is used each day
Daily pre-use inspection
Required with hot work when the permit calls for it, besides a fire extinguisher
Hot work permit and fire watch
Four changes that stop the work until the plan and AHA are reviewed again
Scope, conditions, equipment, or crew
