Stop Use & Recall Notice IMMEDIATE ACTION REQUIRED
3M Fall Protection announces an immediate stop use and product recall of the 3M™ DBI-SALA® Nano-Lok™ edge and Wrap Back Twin-Leg Self Retracting Lifelines. The twin-leg Nano-Lok edge is part of a personal fall protection system and connects two self-retracting lifelines/devices (SRL’s/SRD’s) directly under the dorsal d-ring of a worker’s harness. It is intended to be anchored at foot-level, and is designed for sharp edge applications. The twin-leg Wrap Back Nano-Lok is intended for wrapping around an anchor and incorporates a similar energy absorber. 3M has determined that in the event of a fall and under certain conditions, the energy absorber may not properly deploy which could expose the worker to serious injury or death. Although there have been no reports of accidents or injuries associated with this issue, these products must be removed from service immediately.
To address this situation in the interests of worker safety, 3M is launching a global stop use of the Nano-Lok edge and Wrap Back Twin-Leg SRL units and is recalling all these units to be repaired or replaced as soon as a solution is identified, tested and certified. In the interim, and until a repair or replacement is available, end-users may elect to receive cash for their returned units as described below. This stop use and recall affects all versions of the Nano-Lok edge and Wrap Back Twin-Leg SRL’s since first introduced in 2013.
Users/Owners: Immediately stop using your Nano-Lok edge and Wrap Back Twin-Leg SRL and take these units out of service. Next, go to www. NanoLokEdgeRecall.com and follow the instructions on how to return your unit.
As soon as a product solution is available, 3M will either repair or replace your unit and return it to you at 3M’s expense. Alternatively, and until a product solution is available, you can elect to receive cash in the amount of $200 USD when you return your unit. As an interim solution for applications requiring 100% continuous connection in leading edge applications with sufficient fall clearance, 3M recommends the DBI-SALA® EZ-Stop Leading Edge 100% Tie-Off Cable Shock Absorbing Lanyard. You can also contact 3M Customer Service at 1-833-998-2243 or firstname.lastname@example.org for additional recall information.
You can also contact your local Hercules SLR should you have any additional questions or queries regarding this recall.

MSA is issuing an Inspection Notice to inform you they have identified isolated instances of unflared top eyelet rivets in MSA V-Edge 2.4m Twin Leg Cable PFL. MSA has not received any reports of injuries associated with this condition. However, we are requesting that you perform the inspection outlined in this notice.
An unflared top eyelet rivet may eventually begin to dislodge from the PFL. If the rivet begins to dislodge from the PFL, the PFL may not arrest a fall.
In a review of all riveted connections on PFLs and SRLs, MSA has identified that the field inspections in the following table are to be performed.
Product(See Appendix A* for Part Number list)
Rivet(s) to Inspect (See “Inspection Instructions” section for inspection details)
Number of Rivets per PFL/SRL Assembly (See Appendix B* for Figures showing Rivet Locations)
MSA is committed to safety and quality and has implemented increased inspection and quality controls to prevent this condition in the future.
MSA is advising all customers to inspect the rivets listed in Table 1. Inspect per the Instructions in this Notice. Remove from service any PFL or SRL that does not pass the inspection.
Perform the following inspection to determine whether your PFL or SRL needs to be taken out of service. Please reference Appendix B in the attached Inspection Notice for assistance in locating each type of rivet.
Top Eyelet Rivets
Place the PFL on a flat surface so that there is not a load on the top eyelet rivet.
Attempt to remove the top eyelet rivet from the eyelet by pushing the rivet.
Attempt to remove the top eyelet rivet from the eyelet by pulling on the rivet.
Hold or suspend the PFL such it does not make contact with a surface that would prevent movement of the casing rivets.
Attempt to remove the casing rivets by pushing the rivets.
Attempt to remove the casing rivets by pulling on the rivets.
Shock Pack Rivets
Hold the SRL shock pack such that the shock pack does not make contact with a surface that would prevent movement of the shock pack rivets.
Attempt to remove the shock pack rivets by pushing the rivets.
Attempt to remove the shock pack rivets by pulling on the rivets.
Some small back and forth movement of the rivets is to be expected while pushing or pulling. If any of the rivets are able to be removed from the PFL/SRL, remove the PFL/SRL from service.
Note: If there is a green dot on your PFL/SRL box label or there is a green dot on the end of your rivets, it has already been inspected by MSA and has been determined to be acceptable. No further inspection on your part is necessary.
Replacing Affected PFLs and SRLs
If there is any question about the results of the inspection, remove the PFL/SRL from service and contact Hercules SLR for a replacement PFL and/or SRL.

Yes, it’s a confined space that you need a permit to enter – but a permit-required confined space also:
Contains or has the potential to contain serious safety or health hazards like:
Heat or Cold Stress
CONFINED SPACE HAZARD: 2 FACTORS THAT CREATE HAZARDS
Failure to see and control hazards associated with the confined space
Poor Emergency response time or plan
Many injuries or fatalities in confined spaces occur when other workers attempt to save coworkers injured in a confined space
Nearly 60% of worker fatalities occur when trying to save someone else from a confined space hazard
Nearly 60% of deaths in confined spaces happen to the would-be rescuer
CONFINED SPACE: KNOW THE HAZARDS
Hazard #1: Oxygen Deficiency
Normal air has an oxygen content of 20.8-.9% – when there’s less than 19.5% available, you’re in a oxygen-deficient space. When this level decreases, even by 1-2% the effects are felt immediately. When working in a space with this level, remember to wear a self-contained breathing apparatus (SCBA).
What leads to oxygen deficiency? Inadequate ventilation, poor air quality, oxygen consumed from welding, decomposition, rust are some of the factors that cause oxygen levels to drop.
Oxygen Deficiency Levels
Minimum for safe entry: 19.5%
Impaired judgement and breathing, accelerated heartbeat: 16%
Faulty judgement and rapid fatigue: 14%
Nausea, vomiting, inability to perform simple tasks, unconsciousness: 6-10%
Rapid loss of consciousness, death in minutes: Less than 6%
Hazard #2: Oxygen Displacement
Oxygen displacement occurs when there’s an inert gas (it’s worth noting inert gas is different than a noble gas – an inert gas doesn’t chemically react, and a noble gas does chemically react under certain conditions. All noble gases are inert, but not all inert gases are noble).
When enough of a inert gas is in a confined space, it displaces the oxygen which makes it difficult – well, impossible to breathe. For example, nitrogen is non-toxic, colourless and odourless – but will displace the oxygen in a room.
Hazard #3: Fire & Flammable Atmosphere
Flammable atmospheres are caused by flammable liquids, gases and combustible dusts which if lit, can cause an explosion or fire. The ignition doesn’t have to be a flame – it can be something as simple as static electricity or a small spark.
Hazard #4: Physical
You can become engulfed after being trapped or enveloped by material. Electrocution can happen when electrical equipment is activated, and mechanical energy can activate and cause physical injury.
Other physical safety hazards, although small that can still cause injury are inadequate lighting, noise, vibration and radiation. Nearby traffic, vehicles and other heavy machinery could also be a hazard. Objects and slippery areas pose falling hazards, and hot or cold temperature extremes also pose a threat. Extremely high temperatures can cause your body to undergo heat stress.
Heat Stress Symptoms
In a confined space (and other areas) your body might not be able to cool down which can cause heat exhaustion or heat stroke to occur.
Heat exhaustion symptoms include:
Pale, clammy skin
When these symptoms occur, you should move to a cool area, raise your legs, take off any heavy clothing, drink water and apply a wet cloth to your skin.
Heat stroke symptoms include:
Dry, pale skin – with no sweat
Hot, red skin that looks sunburnt
Unable to think straight, seizure, unconsciousness
When this occurs:
Move victim to a cool area
Loosen or remove heavy clothing
Place icepacks at your armpit and groin
To protect yourself:
Try to work or accomplish physical parts of work during the coolest parts of the day
Use spot ventilation
Use buddy system
Drink cold water – try to drink around every 15 minutes and take frequent breaks
Avoid alcohol and caffeine in high temperatures, and be mindful of medication as this can increase your risk of heat stroke.
CONFINED SPACE: PROCEDURES
Before you start work in a confined space, it’s essential to follow a procedure to control and/or minimize safety hazards and remain safe on the job. Follow this procedure before working in a confined space:
Conduct a pre-entry evaluation (like a discussion with everyone who will be working at the site);
Identify and eliminate potential hazards that can enter the space, both atmospheric and physical;
Use forced air ventilation and use lock out/tag out if necessary;
Complete an entry permit – Assign an entrant, attendant and supervisor and any other relevant competent person needed on the site.
The Authorized Entrant will:
Know hazards that will face workers during entry;
Wear proper PPE;
Maintain communication with the attendant;
Know the signs of overexposure/heat stress and stroke;
Evacuate the confined space when ordered to or when over-exposed to hazard(s).
The Authorized Attendant will:
Keep their position outside the entrance at all time;
Know the signs and symptoms of overexposure;
Prevent unauthorized people from entering the space;
Maintain communication with entrants;
Begin the emergency response/rescue plan if needed;
Complete an evaluation of the entrance before they start work;
Make sure personnel know the hazards;
Implement any necessary control measures, for example – ventilation;
Complete any permits that are necessary to enter the space;
Complete any tests needed to enter the confined space safely.
REMEMBER TO use retrieval equipment to remove yourself or the entrant from the confined pace.
Ensuring you have the necessary PPE for emergency rescue situations is the most important step of working in a confined space.
As we mentioned, almost 60% of confined space deaths happen to someone trying to rescue a coworker – It’s natural to want to save a life, but it’s important to not take two lives in the process. This is why confined space planning is essential to completing work efficiently and safely.
Choosing and having the proper PPE for the job is essential to staying safe amidst hazards in a confined space. This may include self-retracting lifelines, anchorages or body harness’ – click the link below to find out more about Hercules SLR’s fall protection services.
