2013 BUILD SAFE | LIVE SAFE CONFERENCE

Course DescriptionNew York City is a vertical city with more than 60,000 elevator stocks

that make 30 million trips each day. Elevators are designed to

transport people in more than 28,000 buildings across New Yorks

dense urban environment.

Maintaining and repairing vertical transportation systems are essential

in providing safe and reliable service to riders and building operations.

A lack of maintenance and repairs may cause elevator failure, reduce

the lifespan of equipment, entrapment and injury.

This course will examine the NYC Building Code and ASME A 17.1

requirements for the maintenance of elevators and escalators. It will

also discuss best practices for maintenance and repairs; includingengineering controls and accident prevention.

Learning ObjectivesAt the end of this program, participants will have learned:

Participants will examine NYC Building Codes requirements administrative

section 28-304.7 and ASME A 17.1 SECTION 8.6 for elevators and

escalators in order to be able to identify specific regulations for elevator

maintenance and repairs.

Participants will examine the Maintenance Control Program and be able to

keep a Maintenance Log that is reflective of manufacturers and code

requirements.

Participants will review best practices for the maintenance and repairs of

elevator and escalators in order to educate on the potential risks while

working on equipment.

Participants will analyze various design and engineering control methods toenhance public safety during maintenance and repair.

Safety Tip

A few over-the-counter drugs like antihistamines,

cough syrups, and cold medications can create

drowsiness. During allergy season, take notice of the

side affects and adjust use accordingly.

CAUTION TAPE (NYC)

The code specifies 3 yellow caution safety tape installed at 18

and 54 on the inside car door threshold when working on the

elevator

The tape needs to be utilized when the elevator is removed from

normal service and a Mechanic is not working in front of the

entrance of the actual device

Prevents unintended public entrance

Lights out/Doors open communicates that the car is out of

service

DEEP PIT PROTECTION

Pits designed with bottom landing access points

represent a challenge for public protection

Falls of any height can cause injury

Deep pit depths can be as great as 20

ELECTRICAL HAZARDS

If electricity is required for the task, the mechanic must work

safely around it.

Increase distance from the hazard

Temporarily guard the hazard

Permanently guard the hazard

JUMPER MANAGEMENT

Jumpers must not be used as a diagnostic tool

Temporary bridging devices must never be used to short out hall door

contacts. Exceptions must have a written JHA approved by supervision.

Never jump-out door and gate contacts at the same time.

Ensure that elevator is on inspection prior to placing jumpers on door,

gate, or safety circuits.

another party

Retrofitting of permanent guards is an owner decision

Use of temporary guarding is a best practice

y p

Minimum Operational Requirements

Comply with Federal, State and City regulations

Develop a Culture of Safety Develop a Safety Management System

Proactively manage safety through

Employee training & communication

Proper safety equipment & tools

Create an environment where mechanics champion safety

Empower mechanics to own safety

Support the safest work, not the fastest

Vehicle Management/Driver Accountability

Invest in the safety program

Standardize Processes


70/78


When practical, document a standard work process

Develops efficiencies

Improves safety for all

Reduces re-work and unproductive time

Establish the Rules


71/78


ALWAYS use fall

protection when a fall

hazard exists.

ALWAYS lock and tag

out equipment when

power is not required.

ALWAYS establish and

maintain control of the

unit prior to accessing.

ALWAYS follow proper

jumper procedures.

ALWAYS use certified

& inspected hoisting &rigging equipment.

ALWAYS follow the

operation authorizedprocedures for false

cars/running platforms.

Establish the Rules


72/78


ALWAYS control live

electricity and rotating

equipment when working

within close proximity.

NEVER ride the car top

with the elevator in

normal operation.

NEVER work above or

below others when

working in the hoistway.

ALWAYS use barriers andredundant controls

(LOTO) when unattended

ALWAYS secure thestep chain from

movement.

NEVER ride escalator

when steps are removed.

Educate Mechanics on the Process

Job Hazard Analysis (JHA)


74/78


An important accident

prevention tool used by

mechanics is the Job Hazard

Analysis Process, or JHA.

This process allows mechanics

to analyze each job step,

identify hazards they may

encounter, and document waysaccidents can be prevented by

mitigating these hazards. A

written JHA should be used at

the start of each day, and whenstarting each new major task.

a. Scaffoldingb. False Cars / Running Platformsc. Hoisting & Riggingd. Jumpers

Although NEII companies

continue to drastically reduce

the number of injuries, serious

injuries still occur.

As a result, some members

have developed special

observation programs to

assess the level of

understanding of mechanics ofthe key hazard areas while

performing typical procedures.

This assessment focuses on

preventing the leading causesof serious and fatal injuries.

Program Recognition & Enforcement


76/78


Mature programs

Motivate employees to do the right thing

Reinforces compliance to rules

Formally document history

Verbal warning to termination options

Automatic suspensions for violations, even first time
