2320 Material Handling and Storage Flashcards
What 4 questions can be used to understand the product movement/transportation system being used in a warehouse?
What type of product packages are being handled?
What is the direction of transport in the facility?
What is the mode of transport?
What transport equipment is being used?
List 7 common material handling tools.
Hand trucks Pallet Jacks Lift Tables Conveyors Overhead Rail Systems Stair Climber Vacuum Lifter
Are back belts PPE for lifting?
No.
There isn’t strong evidence to indicate whether back belts make a difference in the risk of injury. As such, WorkSafeBC does not consider them to be PPE.
What are the most common styles of storage racks?
1, Pallet Racks
Simple shelving designed for pallets or large units of materials
2, Drive-In/Drive-Through Racks
Large racks intended for use with a lift truck (or similar)
3, Cantilever Racks
Bracket-like arms that long items can be placed on.
4, Special Racks
Usually an adapted version of one of the other systems.
What standards are relevant in storage rack systems?
Most OHS regulations and building codes require RMI/ANSI standard steel racking.
ANSI usually adopts RMI standards for steel storage racks.
RMI is the Rack Manufacturers Institute.
What 4 critical safety items should be considered with storage racking?
1, RMI/ANSI approved or another acceptable standard.
(Rack Manufacturers Institute, American National Standards Institute)
2, Rack components strong enough for intended load.
3, Rack height is stable.
4, Racks guarded against contact with machinery (such as damage from lift truck collision)
What is ANSI?
American National Standards Institute
What is the RMI
Rack Manufacturers Institute
Contrast storage shelving vs storage racks.
Storage shelving is for smaller/lighter materials.
Racks are for larger/heavier materials.
What are the 4 basic configurations of storage shelves?
1, Open shelves
- Sides and back of shelving is open
- braces may help to stabilize
- floor mounted
2, Closed shelves
- sides and back panels present & add stability
- floor mounted
3, Ledge Shelves
- may be open or closed
- 2 or more units, where the lower is deeper resulting in a ledge/counter space
- floor mounted
4, Counter shelves
- shelving mounted on a counter instead of the floor
- may be any other type (open, closed, ledge)
What standards are relevant in storage shelving systems?
SEMA (Storage Equipment Manufacturers Association) & ANSI produced two standards.
1, industrial steel shelving
2, metal-wood shelving
What is an AS/AR system?
Automated Storage/Automated Retrieval system.
What is an AGV?
An automated guided vehicle.
Used in highly automated facilities to store and retrieve materials.
What safety considerations are generally important when working with AS/AR systems?
Automated systems are powered, and as such introduce the hazard of workers coming into contact with the energy of the system.
Effective guards are required to protect workers from accidental contact with system energies.
Effective de-energization processes are necessary.
What safety items should be inspected on racking/shelving systems?
- Conformation to design standards
- Load capacity vs actual; load
- Bracing/stabilization components in place and good repair
- Structural components in place and in good repair
- End/corner guards are in place
- If evidence of damage to guards, then review worker training (lift trucks)
- Materials stored is stable
