We
recently had our elevator code update continuing education class and here are
some of the items that stuck out when reviewing the 2019 code books. These 10 hours are one of the highlights of my
year. While listening to a code class for
10 hours is long, we learn so much and we learn more when we all share our
experiences. These are a few snippets
from my notes, some are not new code items but good to remember.
A17.1 – 2019 – New Construction & Modernization
Hoistway access switches - between 48” and 72” AFF[2016 requirement] within 12” of hoistway door frame
Reopening devices for power sliding doors and gates - 3D door screens – The device shall be effective while the doors are closing to within 18” or less of the fully closed position.
Emergencyoperation and signaling devices – requirements for a means for emergency personnel within the building to utilize the car station display (for texting) and a car station camera (for visual confirmation) for buildings with a travel of 60 ft or more.
A17.3 – 2019 – Existing Elevators
Hoistways - The hoistway does not need to be fire-rated if it was not required when the building was erected.
Hoistway entrances – Vertical door applications shall have a fire-resistant, non-shearing, non-crushing astragal on the full width of the upper panel.
Hoistway door locking devices, parking devices and access - Every passenger elevator shall have a door restrictor which limits the opening of the door 4” when the elevator is outside the locking zone (not more than 18”).
Counterweights - All counterweights shall be designed so that the weights cannot be dislodged at any time.
Car frame and platforms - Wood platforms are permitted for capacities up to 5,000 pounds.
Protection of platforms against fire - Wooden platforms shall either have a sheet metal bottom or be painted with an approved fire-retardant paint.
Car enclosures - Car door interlocks shall be provided when the running clearance exceeds the minimum requirements.
Governor rope - Governor ropes shall be minimum 3/8”, be manufactured with metal and have regular lay.
Capacity & loading - The minimum rated load shall be no less than 50 pounds per square foot, passenger elevators – 110lbs.
Operating and control equipment - The disconnect shall be in sight of the controller and either the motor-generator set or the hoist machine. A remote manual switch shall be provided to prevent starting when proper line of sight is not provided for all three.
Driving machines – Hydraulic elevator - Designs which have a portion of the cylinder not exposed and do not have a safety bulkhead shall have one of the following:
- Monitored cathodic protection
- Proper cylinder coating.
- PVC casing.
- Or a Life Jacket, safety device or equivalent.
Always learning – Here is my little sales pitch for everyone about life long learning. When you learn, you take a job, the job becomes a career, the career becomes a passion. If you work in a place or industry that you are passionate about you no longer count the hours, days, etc because you are good at what you do and love it. It doesn’t matter if you are an ice cream scooper or a CEO of a multinational firm, we all need to keep learning. Try not to be the person who hasn’t learned anything since they graduated high school, this person refuses to do anything to enrich themselves and becomes angry about their position in life. You! And only You! Can make a difference in your life. We do not need anyone else from Mordor.
