The 2018 Edition is here and once again, change is a constant theme. From both minor and major revisions, to new additions and major reorganizations, the 11th edition contains many changes.
Earn 0.2 CEUs / 2 PDHs by watching the video, reviewing the workbook and taking the exam at the end. Upon completing and passing the exam, a certificate of completion and course transcript will be sent to you.
Many global changes found throughout the 2018 edition include:
All mathematical symbols are replaced with alpha numeric values. i.e. “>” is now spelled out as “greater than”
cal/cm^2 are the primary units and J/cm^2 is in parenthesis.
A greater emphasis is placed on risk assessment.
Job Safety Planning was added as a new Section 110.1(I)
All training requirements are now located in 110.2. This includes relocating Lockout-Tagout training from Article 120.
All Lockout/Tagout auditing requirements were relocated to 110.1(K)(3).
In order to continue improving the standard to be more user friendly, Article 120 has been reorganized for a more logical flow.
Other changes include the deletion of the informational note regarding de-energizing above 40 cal/cm^2
The list of PPE standards has been removed from the mandatory part of the standard are re-located in informational text. Conformity assessment requirements are now part of the mandatory language.
