TYPES OF WORK EQUIPMENT USING ABRASIVE WHEELS? These items are not included Why www.safetygoodwe.com 9 11-12-2023

10

HAZARDS • Coming into contact with moving parts of the equipment (including abrasive materials). • Wheel/Disc bursting and material being ejected. • Abrasive and small particles coming into contact with eyes. • Noise from equipment. • Vibration from equipment. • Kickback where the grinder is thrust away from the work piece. • Inhalation of fumes and dusts from materials being worked on. • Entanglement with loose items drawing grinder to the operator • Electrocution (PAT TESTING ) 12/11/2023 www.safetygoodwe.com 10

11

ACCIDENTS • Contact Injuries 60%: • Touching wheel, burns, cuts, gashes, possible • Amputations, inadvertent, behavioural. • These can be prevented by training in the correct use. • Eye Injuries 30%: • Caused by lack of eye protection – • Must be impact 1grade Goggles or Full face visor Grade 1B • These injuries can be prevented by wearing the correct PPE and deploying the guard/deflector as trained • Burst Wheels 10%: • Various Causes, Manufacturing defect ,incorrect use, behavioural, • incorrect disc for application of work . 12/11/2023 www.safetygoodwe.com 11

12

RIGHT TOOL FOR THE TASK • Is use of a portable angle grinder/cutter the right option for task. • Has the grinder the following designed safety features?: • Soft start option (wherever possible) • Deadman’s handle (incorporating auto disconnect lock on facility). Deadman’s handle is mandatory (If it comes with a lock on switch this must never be engaged by the user). • Left- and right-hand operation as standard. • Is the size of the unit correct for the task consider weight, ergonomic design, task position, extent of work, work periods, rest periods, restricted working space? • Is the guard in place and set to correct position in good condition and secure? • If the answer is no to any of the above, consult Industrial Safety before proceeding 12/11/2023 www.safetygoodwe.com 12

13

HOT WORK Grinding /cutting is classed as hot work and will require a hot work certificate in accordance with BEG/SPEC/SHE/CSI/042 Hot Work www.safetygoodwe.com 13 11-12-2023

14

• Guarding is provided to contain fragments of the wheel that might fly off if it did burst so preventing injury to the user and others in the workplace • The guards secondary use is deflection of the debris and sparks away from the operator • Operators suitably trained in the correct handling and mounting of abrasive wheels (This is for portable grinders only) • Correct mounting will reduce the risk of bursting. Control Measures Guard Fitted www.safetygoodwe.com 14 11-12-2023

15

PERSONAL PROTECTIVE EQUIPMENT • Mandatory PPE requirement • Kevlar Sleeves • Wide vision goggles, Offer eye protection and also prevent dust and debris entering users eyes or/and Full face visor as an alternative offers full face protection but is not sealed against dust and debris • impact rated to BS grade 1 or EN grade B • Consideration should be given full face fitted respiratory units or indirect vented goggles to prevent dust ingress • Heavy duty gloves (Riggers leather) as a compromise is required that allows user to hold and maneuver the grinder during use • Rated for mechanical protection • EN 388 • Abrasion rated 3 or greater • Cut rated 4 or greater • Tear 2 or greater • Puncture 1 or greater 12/11/2023 www.safetygoodwe.com 15

16

PERSONAL PROTECTIVE EQUIPMENT • A Kevlar fibre knitted sleeve with or without the cowhide split leather reinforcement on each arm • Hearing defenders due to high noise levels • Fire retardent workwear close fitting, no loose cords that may become entangled and draw the angle grinder/cutter into the user • Long hair/jewellery - tied back/made secure • Task risk assessment may require further protection:- • Hood to protect against particles been ejected or bounced back in restricted spaces • Respirator when the material or coatings may be harmful to the operator • Leather apron/jacket may offer protect to lower body and chest area (although may not be practical) 12/11/2023 www.safetygoodwe.com 16

17

Grinders and use on Non ferrous items • Abrasive (grinding wheel) composition may be compromised by the heat generated by a "clogged" wheel. The heat is usually carried away from the wheel in the metal it removes, but a clogged wheel becomes a heat generator and the metal adhered to the wheel seals the heat in, therefore you could see a wheel explosion when the material is in contact with the wheel. • Examples of material that will clog discs • Copper • Brass • Aluminium • Paint coatings • Always select the right disc for the material to be worked on if in doubt refer to manufacturer 11-12-2023 www.safetygoodwe.com 17

18

PERSONAL PROTECTIVE EQUIPMENT Heavy duty rigger gloves are suitable the gloves must be flexible so as not to compromise the feel of the user Heavy duty gloves Kevlar & Leather Sleeves Worn when Using grinders may be worn over or under overall sleeves www.safetygoodwe.com 18 11-12-2023

Task: Cut reinforcing bars from box-out in concrete wall. Work Equipment: 4” Angle grinder fitted with steel cutting disc. Personnel: Experienced General Labourer trained in abrasive wheels. The operative requested a new pair of gloves from the stores but the expected delivery hadn’t arrived yet. The operative went to stores to collect an angle grinder, the only one available had its guard removed he took it anyway. Unknown persons previously using the tool removed an angle grinder guard. Instead of continuing to use the gloves he already has the operative doesn’t wear gloves whilst carrying out the task. Accident happens, and operative received injuries which resulted in him losing sections of his fingers and becoming disabled for the remainder of his life. GUARDS – CONSEQUENCES OF NOT USING!!!! www.safetygoodwe.com 22 11-12-2023
