Changes to the ANSI Aerial Lift or Mobile Elevating Work Platform (MEWP) standard A92.22 for Safe Use and 92.24 Training were published December 2018 and will go into effect March 2020. The changes affect design, user safety and training.

Here are some quick points that will affect MEWP owners, operators and supervisors.

  • There are 2 Groups of platforms and they subdivided into Types within each Group.
  • Owners, operators, occupants and supervisors must meet new training requirements.
  • All personnel who will operate, supervise or train operators, must receive training that meets the new standard requirements.
  • MEWP Operators will be required to instruct or ensure all occupants have a basic level of knowledge of work safety on the MEWP.

All MEWP operators are required to update their training to meet the new requirements. Training should include:

  • Classroom/theory
  • Practice – demonstration of skills
  • Evaluation of knowledge and skills

Dealers and rental companies must, if requested, offer familiarization training to customers who rent, lease or buy MEWPs.

Here are some changes manufacturers must make to become compliant.

  • New MEWPs must have a gate entrance. A chain will no longer be accepted.
  • Rough terrain models will be required to have foam filled or solid tires.
  • Equipment railing height is changing to 43.5 inches.
  • If the safe weight limit is exceeded, an alarm will sound, and the operator will be required to make changes before the unit will operate normally again.
  • Tilt sensors will monitor safe limits.
  • Outdoor units will be fitted with wind-speed sensors.


MEWP Groups and Types Simplified


scissor, lift, aerial, mewp

Group A MEWP with platforms that move vertically but stay inside the tipping lane.

Group B, all other MEWPS, where the platform extends past the chassis.


Type 1 – Can only be driven from the stowed position

Type 2 – Can be driven elevated, but is controlled from the chassis.

Type 3 – Can be driven elevated, but is controlled from the platform.


A few of the Safe Use requirements of MEWP owners are listed below.

  • Develop a safe use program;
  • Arrange for proper and timely maintenance and inspections in accordance with the manufacturer recommendations;
  • Conduct a risk assessment and site safety plan that is to be documented and shared with operators and work site personnel.
  • Provide training to supervisors, operators and occupants
  • Develop rescue plans
  • Comply with components of the


The full requirements can be found in ANSI standards A92.22 – 2018 Safe Use and A92.24 – 2018 Training requirements.


And since MEWPs require fall protection, make sure fall protection training is up to date as well.
