This is what LO/TO stands for?
What is Lock Out/Tag Out
This is the form you use to lift anything weighing 500lbs or above AND being lifted above head Regardless of lifting equipment
NM Critical Lift Plan
This is the depth that you need an Intel Excavation Permit to dig
What is an Excavation permit.
Excavation Permits are required at 6” or greater.
This document is required to be accessible when chemicals are being used onsite
What is an SDS?
These three characteristics defines a confined space
Is large enough for an employee to enter and perform work
Has limited or restricted means for entry or exit
Is not designed for continuous occupancy.
This is when it is okay to give someone the key to your lock?
What is NEVER.
Remember it is your lock and your key! Your life is on the line when working on the affected system.
These two things make a crane lift a Critical lift
What is Lifting more than 75% of the crane capacity and Use of multiple cranes.
These are the three main types of protective systems used in trenching
What is
These are what the 4 colors of the NFPA Diamon represent
What is Flammability hazards for Red, Health Hazard for Blue, Instability for Yellow and the Specific Hazard in White
This is the difference between a confined space and a permit-required confined space
A permit-required confined space has all the characteristics of a confined space and one or more of the hazard
This is the form used to remove locks that have been abandoned in the field.
What is an Abandoned Lock Form.
These forms are a last resort to resolving locks that have been left behind. You must make at least two attempts at calling the person who owns the Lock and tag.
This is how often is a pre-lift meeting is required
What is prior to daily crane activities?
This is the depth at which a protective system (shoring, shielding, or sloping) is required in a trench
What is 5 feet.
A competent person may also determine that a system is needed at less than 5 feet if there is a risk of cave-in.
This is what GHS stands for
What is Globally Harmonized System?
What are some common hazards found in confined spaces
Common confined space hazards include
Lack of oxygen or oxygen-enriched environment
Toxic gases or vapors (e.g., hydrogen sulfide, carbon monoxide)
Flammable atmospheres
Engulfment by liquids or loose solids
Physical hazards such as moving parts or extreme temperatures
These are three types of LO/TO devices
Here are a few types we will see:
This Safety device should be fitted (where applicable) to the hook block to prevent sling form dislodging
What is a Safety catch on the mouth of the hook
This is when it is necessary to test the atmosphere inside a trench
What is 4 Feet?
Atmospheric testing is required when a trench is deeper than 4 feet or there is a possibility of a hazardous atmosphere, such as low oxygen, flammable gases, or toxic substances
These five elements are required on the Hazardous Waste container label.
What are the words "Hazardous Waste", list of contents, Characteristic, Contact information (e.g. Co. name & address) and the Date (when full)?
NOTE: Chemical abbreviations are not allowed on the label
Atmospheric testing is conducted to ensure the air in the confined space is safe to breathe and free from which hazardous conditions
Low Oxygen levels
Flammable gases or vapors
Toxic substances
This is the sequence of Locking and Tagging out a system
Before a rigger can select the length and capacity of slings needed to lift a load, these two things must be known
What is the Weight and center of gravity?
This type of soil is considered the least stable in trenching and excavation work
What is Type C soil?
Type C Soil is the least stable and most hazardous type of soil classification used in trenching and excavation work, as defined by OSHA.
It includes:
This is the number of Hazard Classes recognized
What is 9
These are the two responsibilities of a confined space attendant
Monitors the workers inside the space
Maintains communication with entrants
Alerts rescue services if an emergency occurs
Prevents unauthorized entry
