Disaster Responder Roofing Safety - Framework

Disaster Responder RoofingSafetyHarry DietzNRCA Director of Risk Management

What is NRCA? One of the oldest construction trade associations Approximately 4,000 members Roofing contractors, manufacturers, architects,government, & institutional members Involved with technical, safety, governmental &educational issues affecting roofing NRCA involved in Rebuilding Together and othercharitable efforts where volunteers are active

Class Goal To maintain your personal safety and that ofother volunteers and third parties as you work tominimize further property damage in areas thathave been subjected to a disastrous event We do not intend to make you into roofing orbuilding trade professionals, but keep you safeas you help others protect their property untilthose professionals are on the site.

Class Objectives Increase your awareness of roofinghazards generally and in disasterresponse situations specifically Introduce safe work practices and controlmeasures to minimize the risk of injuries Increase your awareness of equipmentand tools to help you safely perform yourwork

Site safety & roof access

Hazard or risk assessment—preliminary site Power lines/electricityOther utilities, propane, natural gasStanding waterStructural integrityTrees, polesDebrisPeople, pets

Hazard controls—power lines– Always assume they are live– Always assume they are not insulated– Keep ladders, scaffolds and workers at least10 feet from lines– Flag and barricade areas where fallen powerlines are on the ground with orange cones,caution tape to prevent contact– Follow instructions of utility workers

Roof access—ladder types

Ladder ratingsType IAA—375 poundsType IA—300 poundsType I—250 poundsType 2—225 poundsType 3—200 pounds

Ladder Setup 1

Ladder Setup 2Ladders must be tied offto prevent movementLadders must extend at least 3feet over the eave or landingsurface

Ladder Setup 3A ladder must be placed on firm,stable and level groundSecuring the base of the ladder helpsensure stability

Ladder Setup 4Rung locks, also called dogs or pawls,must be fully functioning and secureMake sure rung locks are fully seated ontorung —this photo shows improperlocking

Ladder Setup 5—Walking aladder upPlace feet of ladder at the base ofthe buildingWhile putting pressure on the ladderin the direction of the building, pushthe ladder upwards rung by rung

Ladder Use 1 Do not carry anything up aladder Use both hands to hold theladder siderails or rungs Face the ladder when goingup or down Only one person at a time ona ladder Do not load a ladder beyondits rated load capacity

Ladder Use 2 Never stand onthe top or top stepof a stepladder Never use astepladder in theclosed position

Ladder Use 3 Control access toareas around theladder setup point Use the rightladder for thesituation

Roof access—scaffolds Scaffolds canprovide stable roofaccess and stagingareas but requireground clearance Integrated ladderaccess is oftenvertical makingclimbing difficult

Roof Hazards—roof types Low-slope roof,4:12 or less Steep-slope roof,greater than 4:12

Roof typesGable roofHip roof

Roof typesGambrel roofMansard roof

Roof slip hazards

Roof hazards—skylights andopenings

Skylights Not capable ofsupporting theweight of aperson Found on lowand steep-sloperoofs

Openings May result fromflying debris thatdamages roof;roof vents, solartubes or skylightsremoved by forceof wind

Roof hazards—deck integrity Rotten wooddecking can be aserious hazard It is often hard tospot unless visibleduring an inspection Thin 3/8-inchplywood may befound on some roofs

Roof hazards—vent stacks,satellite dishes and cables All posetrippinghazards Lightningarrestingequipment canalso be present

Roof hazards—electricalElectrical service drop on roofSolar panels on roof

Hazard Controls—skylights,openings Cover withplywood, usuallyrequires ¾-inch;larger openingsmay requireadditional framing Secure with nailsor screws

Hazard controls—slip hazardsKorkers Footwear sellsstrap-on versions for use withpersonal footwear Some footwearprovides better gripon roof surfaces These work shoesare designed forincreased grip More on FallProtection shortly

Fall Protection Personal fallarrest (PFA)systems andpersonal fallrestraint systemsare often used inresidentialconstruction

Criteria for PFA’s PFAs often consist of a body harness, anchor,connectors, deceleration device, lanyard andlifeline Each worker must be connected to separatelifeline Lanyards and vertical lifelines minimum 5,000pound strength Anchors must support 5,000 pounds Must limit free fall to 6 feet max Ropes and straps must be synthetic

Personal fall restraint Designed to stopa person fromreaching a fallhazard Some fall arrestsystems can berigged in fallrestraint

Anchors Anchors forpersonal fallarrest (PFA)equipment mustbe capable ofsupporting atleast 5,000pounds peremployeeattached34

Manufacturer’s Installation Instructions Anchors must be installed following theinstructions from the manufacturer Only the type of fasteners described bythe manufacturer for use with the anchormay be used The quantity of fasteners described by themanufacturer for use with the anchor mustbe installed35

Locating Roof Anchors—ResidentialSome General Guidelines Locate at roof peak when possible andat least 6 feet from any exposed roofedge DO NOT install roof anchors onunsupported roof structures, such aseaves or gable overhangs36

Locating Roof Anchors—ResidentialSome General Guidelines Hip roofs may require a roof anchor at eachhip face Reduce swing fall hazards on long roof facesby using multiple roof anchors installed atleast 6 feet from the rake edge Best anchor position is directly above worker37

Swing Fall HazardsSwing Fall HazardGable End Swing Fall38

Slide guards In addition to PFAor personal fallrestraint, slideguards may offersupport and slipprotection

Slide Guards Slide guardsconsist ofmetalbracketsthat securea section ofminimum 2X 6-inchlumber

Hazards of tarped roof? A tarped roof will beslippery especially if wet Cleats, nails, seams andwrinkles will be triphazards Holes and openings thathave been covered overwill not be obvious tosomeone walking on theroof

Power Tools

Hazard: Power ToolsHand-heldelectrical tools areespeciallydangerousbecause theymake continuouscontact withhands.

Ground-fault CircuitInterrupter (GFCI) This device protects youfrom dangerous shock The GFCI detects adifference in currentbetween the black andwhite circuit wires If a ground fault (leakage)is detected, the GFCI canshut off electricity flow inas little as 1/40th of asecond, protecting youfrom a dangerous shock1926.404(b)(1)(i)

Hazard Control: Power ToolsTo protect from shock,burns and electrocution,tools must do one of thefollowing:– Have a three-wire cord with groundplugged into a grounded receptacle– Be double insulated (indicated bysymbol of square within a square)Double Insulated marking

Double insulated symbol

Hazards and ControlsControl: Power Tool Safety Tips Inspect tools before each use Read and understandmanufacturer’s safetyinstructions Use the right tool correctly Use required PPE Store in dry place―don’t use inwet or damp conditions Keep working areas well lit Don’t use damaged tools

Hazards and ControlsControl: Power Tool Safety Tips Ensure no tripping hazard exists Don’t carry a tool by the cord Don’t yank the cord to disconnect it Keep cords away from heat, oil andsharp edges Disconnect tools when not in useand when changing accessories

Personal ProtectiveEquipment (PPE)

Head Protection50

Eye and Face Protection

Eye Protection Eye protectionmust meet therequirements ofANSI Z87.11968 Complianteyewear will bemarked Z87.1

Hearing ProtectionMay be necessarywhen operatingloud poweredequipment or ifsuch equipment isin use in closeproximity

Respiratory protectionExposures to gases,vapors, fumes, dustsand mists maynecessitaterespiratory protection.Some people maywant some protectionagainst nuisance dustby using N-95 dustmasks. Be aware thatuse of respirators,even dust masks, canmake breathing moredifficult. Check withyour doctor.

Hand protection Heavy leatheror rubbercoated clothwork glovesprovide handprotectionfrom nails &other sharpobjects

FootwearKorkers Footwear sellsstrap-on versions for use withpersonal footwear Some footwearprovides better gripon roof surfaces Choose footwearthat has punctureresistant soles You may needgreater waterprotection
