Confined Spaces
Name ONE of the THREE conditions that defines a confined space?
-Large enough to allow a person to enter a space with their whole body to do work
-Limited egress/ingress point
-NOT designed for human occupancy
You want to perform fall protection operations, who do you talk to for approval?
- CO and OOD
What classifies operations as "hot work"?
welding, grinding anything creating spark/heat
What devices can be used for lockout/tagout ?
-Padlocks, safety tags, lockout hasps, group lockout boxes
List the THREE main components that result in a "permit required" confined space?
-Atmospheric hazards
-Physical hazards
-Worker introduced hazards
Name THREE limitations for working aloft.
- wind greater than 30 kts
-ships roll
-thunder/ lightning
-Wet surfaces
-OOD, ET, CME, CO approval
Explain the differences between AIR purifying respirators vs. ATMOSPHERIC supplying
-AIR: REMOVES contaminants in air (gas, vapor, dust)
-ATMOSPHERIC: PROVIDES clean air (SCBA, SAR)
Name two safety items needed for hot work ops (clothing/equipment)?
Welding mask, long sleeves, pants etc.
List ALL personnel that need to be notified for confined space work?
-CME
-COO
-OOD
(Rescue team, authorized entrant/attendant, any other personnel being affected by the work)
Name three ways to mitigate fall hazards aboard the Dyson
-safety chains
-guard rails
-yellow paint
-wet floor signs
Explain the role of the CO, CME, OOD and Competent Person Aboard during hot work operations
CO- ensures all protocols are followed/ gives final approval
CME- certifies space is safe
OOD- Approves and relays info to CO, logs and inspects
Competent Person- Prepares permits/ operations
What is the purpose for lockout/tagout and who is authorized to attach/ remove them?
Physically isolate power sources. Authorizing official.
You are the authorized person watching over two engineers in the owinch rm tank. One engineer suddenly drops and goes unconscious. The other engineer relays the information to you, then suddenly drops just before exiting the tank. What do you do?
-DO NOT enter the tank to help
-Call for help: notify rescue team, monitor atmospheric levels (gear should be staged, help set up rescue)
-Notify CO, CME and medial
Demonstrate ability to properly wear a harness, grab ALL safety gear you will need for fall pro operations
Have selected team member put on harness and lift safety gear needed
You are preparing for hot work ops, what are the prerequisites to proceed?
Inspect spaces, remove flammable material, lockout/ tagout requirements are met, blank off ducts, set up ventilation, notify personnel
Demonstrate the proper fit for an SCBA + harness
Have selected team member dress out
