Missouri construction certification requirements

The safety training Missouri asks of construction crews, rule by rule: what each card is, who needs it, how long it lasts, and the official source to check it against.

OSHA 10 on public works projects

On-site employees must complete a 10 hour OSHA construction safety program, or an equivalent approved by the Missouri Department of Labor and Industrial Relations.

The card it asks for

  • OSHA 10-Hour Construction

    Who needs it
    Every on-site employee on a public works project.
    Issued by
    OSHA
    How long it lasts
    No expiry set by this rule. See the renewal note.
Who it covers
Contractors and subcontractors building public works for any public body, with no dollar threshold. On-site employees are laborers, workmen, drivers, equipment operators and craftsmen directly engaged in the construction. Work by or for utilities regulated by the Public Service Commission is excluded.
Deadline
Within 60 days of beginning work on the project, unless completed before. Someone found without documentation has 20 days to produce it before removal.
Renewal
The statute sets no expiry or renewal. A previous completion counts.
Read closely
The statute's definition of public works includes some utility work done under a Public Service Commission order, while a later subsection excludes utilities under that Commission. Check with the awarding body if your work is for a utility.

Keep Missouri's cards current across your crew.

Currity keeps every card date for your crew and warns you at 90, 60 and 30 days, so a lapsed card turns up on the board before it turns up on site.
