D.6. POWERED TOOLS&EQUIPMENT(For Drilling&Heavy Equipment,see D.7&D.8) L. Applicable ❑ Not Applicable, Not Anticipated
<br /> Site-Specific Notes&Clarifications: Confluence will use bladder pump to purge and sample the monitoring wells.Pressure washing wand utilized by Confluence
<br /> to decon sampling materials.
<br /> ® ! Type of powered tools/equipment: ®General safe work practices for operation of powered tools and equipment:
<br /> M"Power tools" • Inspect before each use to ensure safe operating condition.
<br /> ❑Powered portable equipment • Clear personnel from hazard zone;keep personnel out of the"line-of-fire;'heed warning labels/signage.
<br /> ❑Powered fixed equipment • Arrange worksite for safe access to equipment and sufficient work area clearance for safe use of tool;confirm
<br /> no overhead obstructions;ensure adequate illumination.
<br /> Energy/power source: • Secure long hair/loose clothing/hanging jewelry near moving/rotating parts.
<br /> ❑DC battery or solar powered • Ensure point-of-operation,mechanical power transmission,other moving parts are guarded with protective
<br /> ❑AC electric powered devices(as applicable);do not override interlocks,guards,protective devices.
<br /> ❑120V • Do not make any equipment modifications that create a greater hazard or bypass safety design features.
<br /> ❑240V ' • Use tool/equipment in accordance with manufacturer's use and safety instructions.
<br /> ❑480V • Use PPE and/or other safety protections,as appropriate,for eye/hearing/hand/head/body protection.
<br /> ❑Extension/flexible cords • Provide training or verify operator competency for use of power tool/equipment.
<br /> • Use ventilation,wet methods,respirators,other applicable means to mitigate inhalation hazard.
<br /> ❑Fuel-powered(gas or liquid) • Move power cords/pressurized hoses to protect from damage during tool/equipment use.
<br /> ❑Pneumatic • For spark/heat generating tool/equipment,have fire extinguisher available,remove combustible/flammable
<br /> ❑Hydraulic materials,or use other means to control fire hazard(e.g.fire watch,fireproof blanket).
<br /> ❑Gunpowder-actuated • Use safe lifting practices and/or lift aids for moving heavy portable equipment,and use safe operating
<br /> Hazards of Power Tools and procedures to protect from acute strains/sprains,overexertion,and cumulative trauma injuries.
<br /> Powered Equipment:
<br /> • Implement safe work practices for compressed air,pressurized systems(pneumatic/hydraulic),stored energy.
<br /> ❑Additional requirements for power tools:
<br /> ❑Eye/hand/body injury • Use vise/clamp/work bench or other means to hold/secure a portable/moveable work piece.
<br /> ❑Point-of-operation hazards • Don't carry electrical tools/equipment by the power cord;don't carry pneumatic tools by hoses.
<br /> ❑Pinch points,moving parts • Disconnect tool/equipment from power source before changing bits,blades or making adjustments.
<br /> ❑Line-of-fire hazards,struck by ❑Additional requirements for fixed powered equipment:
<br /> ❑Fire/explosion,ignition sources • Implement lockout/tagout controls for repairs/adjustments/tooling changes.
<br /> ❑Burns from hot surfaces,steam • Equip pneumatic hoses with whip checks;ensure factory fittings are used for high-pressure hose connections.
<br /> ❑Noise
<br /> ❑Inhalation/atmospheric hazards ❑For climbing/fall hazards associated with large equipment,see D.4."Fall Hazards."
<br /> ❑Working at heights,falls ❑For electrical hazards,see D.10."Electrical Work Tasks."
<br /> ❑Overhead obstruction(s) ❑For ground surface penetration,see D.11."Utility-Related Hazards."
<br /> ❑Musculoskeletal hazards ❑For fuel-safety practices,see D.14."Commercial Chemical Products."
<br /> ❑Potential(stored)energy ❑For air monitoring of atmospheric hazards,see Part E,"Air Monitoring,Worker Exposure Monitoring."
<br /> ❑Illumination
<br /> WELDING,CUTTING,HOT WORK E ❑General safe work practices for operators of welding equipment:
<br /> ❑Arc-welding(electrical arc) • Hot work permit system shall be implemented.
<br /> ❑Gas-welding/cutting(fuel gases) • Operator properly protected(eye protection,clothing,apron,etc.).
<br /> Hazards: • Fire hazard controls(watcher,fire extinguisher,water,remove combustibles from work area).
<br /> UV/IR light-eye/skin burns • Protect nearby personnel from hazardous UV,IR light(shielding,curtain);see D.16."Radiation Hazards."
<br /> hot-work hazards/fire ❑For welding gas cylinders,secure them upright with caps on when stored or not in use;protect cylinders from
<br /> toxic metal welding fumes damage;NEVER secure gas cylinders to metal welding bench used for electrical arc welding;
<br /> compressed gases(physical see D.14."Commercial Chemical Products."
<br /> hazards,fire,oxygen deficiency) ❑For arc welding,follow electrical safe work practices;see D.10."Electrical Work Tasks."
<br /> electrical shock ❑For inhalation hazards from welding fumes(toxic metals)and gases(asphyxiant,flammable),see D.14.
<br /> "Commercial Chemical Products."
<br /> PORTABLE ELECTRIC GENERATOR i ❑Follow general safe work practices for Powered Tools&Equipment(above),and as follows:
<br /> Hazards: • Use in accordance with manufacturer's instructions,including instructions for grounding the generator.
<br /> Electrical shock • Keep generator and work area dry.
<br /> Carbon monoxide inhalation • Never use indoors,or near building air intake vents due to carbon monoxide hazard.
<br /> hazard • Provide for ventilation and/or air monitoring where hazardous accumulation of exhaust emissions is possible.
<br /> Fuel-related fire hazard • Use hearing protection in close proximity to operating generator(where noise level exceeds 85 dBA).
<br /> Injury from mechanical or lifting • Use power cords/extension cords specified by instructions.
<br /> hazard • Use ground-fault circuit interrupters(GFCls)in accordance with manufacturer's instructions;see D.10.
<br /> Burns from hot surfaces "Electrical Work Tasks."
<br /> '• • Shut down equipment before refueling;see safe practices for flammable/combustible liquids in D.14.
