OSHA has not specified any time frame for required retraining or recertification for Mold, Mold Prevention, and Mold Remediation. Since there is no OSHA standard dealing with this specific hazard the OSH Act general duty clause, section 5(a)(1), 29 U.S.C. 654(b)(1) defines the standard which provides that:
(a) Each employer –
(1) shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees.
A recognized hazard is a danger recognized by the employer’s industry or industry in general, by the employer, or by common sense. The general duty clause does not apply if there is an OSHA standard dealing with the hazard, unless the employer knows that the standard does not adequately address the hazard.
