Roger Williams University Procedures for Unplanned Power Loss in Academic Laboratories, Workshops, and Art Studios 

Unplanned power loss in academic laboratories, workshops, and art studios can potentially cause many kinds of damage, including damage to equipment, environmental contamination due to inoperative air emissions control equipment such as fume hoods or dust collection units, illness or injury to invertebrates/vertebrates, and/or the loss of student, staff, and faculty research and projects. Planning response actions in advance and executing them safely during a power loss even can help prevent these kinds of damages from occurring. 

Reminder: Notify 91�������� Public Safety of all emergency situations at 401-254-3333 

Step 1: Immediate Response to Unplanned Power Loss 

• First: Address immediate potential hazards 

  • Immediately halt all experiments/projects/processes in progress 
  • Shut off any radios, TVs, or other listening/watching devices 
  • Shut off all open flames and fuel sources, including natural gas valves, Bunsen burners, cylinders, and butane canisters for biosafety cabinet usage 
  • Shut off all thermal, laser, and UV devices in use, including hot plates, microwaves, UV gel readers, lasers, CNC Mill, close liquid nitrogen dewars, etc. 
  • Shut off and/or put down any hand, power, or tabletop tools 
  • Close, cover and secure all chemical containers, cylinders, biological containers, specimens, agar/growth plates in correct storage areas (do not put in fume hood or biological safety cabinet if the units are showing low or no flow) 
  • Place any broken glass or sharps into their designated waste collection containers 
  • Place any live invertebrates or vertebrates back into their tank or container and secure lid/door in usual manner 
  • Close fume hood sashes 

• Second: Address items which can be hazardous upon start-up 

  • Shut down and unplug any active items which may create a hazard by starting up unexpectedly or unattended (dust collection systems, UV gel reader, centrifuge, rotovap, 3-D printers, etc.) 

• Third: Address items which can be damaged by starting up unexpectedly 

  • Shut down (and unplug as needed) any electronic equipment which could be damaged upon restart (computers, microscopes, table tools, etc.) 

Step 2: Short-Term Response to Unplanned Power Loss 

• Students (including work studies, research students, assistants, etc.) must leave the building unless otherwise approved 
• Lock all labs, shops, and studios which have been safely “closed out” using the above procedures and do not allow use/access until further notice 
• Notify EHS of any special storage or waste needs 
• Only work directly supporting emergency management/power restoration is permitted in the labs, shops, and studios until the issue has been resolved, or unless otherwise approved 

Additional Short-Term Response Actions Specific to MNS: 

• Have designated representatives from each department/lab/etc. check all chemical storage areas, biological storage areas, refrigerators, and freezers. Determine which units do not have power and what are the necessary timeframes for relocating stored items to prevent loss or damage (e.g., -80 freezer items OK for 3 hours, refrigerator items OK for 2 hours) 
• Activate initial steps of IACUC Emergency Animal Care Plan 
  • Designated representative check on status of vertebrates, seawater pumps, oxygen in tanks, etc. Correct immediate needs, and determine needs for next few hours, as well as for 24 hours out, 48 hours out, etc.
  • Activate call chain 
  • Determine which 91�������� faculty/staff (non-student) are available to meet animal care needs for next few hours, 24 hours out, 48 hours out, etc. - keep to a minimum while still safely meeting staffing needs 
  • Dry ice and liquid nitrogen can only be used as specified by manufacturer to keep items cool - do not allow these chemicals to openly off-gas into closed room or closed freezer, refrigerator, or walk-in - this practice can create serious potential inhalation hazards for employees 
  • Place “OUT OF ORDER” signs on any fume hoods or biosafety cabinets which are not working. Close any chemical/biological containers needing fume/organism control in air-tight container and move to separate safe, designated storage area. 

Step 3: Long-Term Response to Unplanned Power Loss 

• Refer to the University’s Emergency Response Plan (ERP) (link included in "Links" section below)
• MNS: Continue to follow IACUC emergency procedures and protocols in addition to ERP

Shellfish Farm Cage Handling Procedures - Notification of Working Environment Hazard and Risk Reduction Steps (April 2023) 

• Work Group: MNS CEED Shellfish Farm employees and supervisors 
• Work Task: Manual handling of shellfish cages (bringing up cages from underwater by hand) 
• Hazard: Recreational anglers are getting fishing lures and hooks snagged on the shellfish farm cages. The lures/hooks get caught on the cages and are not easily visible underwater. The lures/hooks can cut or puncture your hands when you pick up or move the cages. Cut and puncture wounds from metals carry the risk of infection, such as tetanus. 

Risk Reduction Steps: 

1. Complete all required training before completing any tasks.
2. Always wear the correctly-sized waterproof cut/puncture gloves provided for this task. Never handle cages without these gloves.
   1. Follow supervisor instructions and manufacturer requirements for glove use, care, storage, and donning/doffing (putting on/taking off). 
   2. Visually inspect gloves for signs of wear/tear/degradation prior to each use. Do not use damaged or incorrectly-sized gloves. 
3. If you are able to do so, visually inspect the cage area where you are placing your hands prior to doing so. 
   1. Check for signs of caught fishing line, hooks, or metallics/bright paint that could indicate a lure/hook.
   2. Do not touch areas that appear to visually indicate a hook might be present. 
4. Visually check all cages for fishing line and lures/hooks after bringing them up to shore and prior to additional handling. Remove and dispose any visible lures/hooks from the cages before re-deploying. 
   1. In addition to the waterproof cut/puncture gloves, wear ANSI Z87.1+ rated safety glasses when removing lures/hooks 
   2. Use a hand tool you have been trained to use, such as needle-nose pliers, to remove the lure/hook from the cage. 
   3. Immediately place the lure/hook into disposable small corrugated cardboard box or plastic container, close the container, and dispose of the container in the trash. 
5. All Shellfish Farm team members (students, volunteers, and employees) are strongly encouraged to have an up-to-date tetanus vaccine.
6. All Shellfish Farm team members (students, volunteers, and employees) are required to have up-to-date CPR and First Aid certifications on file with CEED. Example fish hook hand injury // Photo credit: Reddit Ferrycliffe Farm shellfish cages // Photo credit: 

91�������� Website Waterproof Cut/Puncture Glove (WCPG) Information 

• All waterproof cut/puncture gloves (WCPG) used by 91�������� Shellfish Farm Team members for handling shellfish cages must be reviewed and approved by 91�������� EHS and 91�������� MNS/CEED Shellfish Hatchery staff prior to use to check for acceptability (protection level, fit, and function). 
• Regular work gloves are not to be used as substitutes for approved WCPG. 
• 91�������� must provide WCPG to Shellfish Farm Team members to use while on the job. 
  • Here are several links to the currently approved WCPG manufacturer websites. Any sample vendor links are included as a reference and are not an endorsement of a particular vendor. 
    • Currently In-Use WCPG – Field-Tested and Preferred by Shellfish Hatchery:
    • Currently Approved Alternative WCPG – Reviewed and noted as providing an appropriate level of protection if In-Use gloves are not available: ,

WCPG Use, Storage, and Care 

• Store the gloves either hanging up to or lying flat to dry in closed in a cool, dry, location out of direct sunlight, water, and chemicals. 
• Try on gloves and review the manufacturer information on sizing/fit to determine the size that best fits you. A snug, but not too tight, fit is the goal – one that allows for full range of motion through fingers and wrists (too tight can be painful over time) but is not loose (loose fabric can get caught/tear on equipment). 
• Visually check for tears, degradation, holes, and other damage prior to use. Do not use damaged WCPG. Obtain a new pair from your supervisor and throw away the old pair in the regular trash. 
• Follow all manufacturer recommendations and guidance. 
  • (includes printable measurement guide) 

Safety Glasses Information 

• All safety glasses used by 91�������� Shellfish Farm team for removal of fishing hooks from shellfish cages must carry the ANSI Z87.1+ rating. Tinted/polarized lenses are not required but may be a personal preference for users working outdoors, particularly on/near the water, where the lens polarization treatment may assist with clearer viewing when looking at objects underwater.
• Regular prescription eyeglasses and regular sunglasses that do not have an ANSI Z87.1+ rating are not to be used as substitutes for safety glasses. 
• 91�������� must provide ANSI Z87.1+-rated safety glasses to Shellfish Farm Team to use while on the job; Shellfish Farm Team members who have their own personal prescription safety glasses or personal safety glasses may choose to use those, provided they are ANSI Z87.1+-rated 
• Here are several links to different sample safety glasses, manufacturers, and vendors. These sample listings are not approved lists or endorsed lists, but are provided as examples of acceptable glasses. Note that “OTG” indicates “Over-the-Glasses” style, meaning they can be worn over a pair of prescription eyeglasses.
