OSHA 29 CFR 1910.134 requires a medical evaluation by a physician or other licensed health care professional (PLHCP) before any worker is fit tested or uses a required respirator. On construction sites, 1926.103 applies the same rule.
The requirement covers every required respirator, from a disposable N95 used for light fume to a full-face respirator. Clearance comes first; the fit test and training follow.
Your employer's hazard assessment and exposure monitoring decide what you wear. Common situations:
Fume from welding and cutting, especially in enclosed spaces or on stainless and coated metals. Often handled with particulate respirators (N95 or P100) or a respirator under the welding hood.
Metal dust and grinding debris before and after welding.
Blasting usually calls for an abrasive-blasting respirator — typically a supplied-air hood. Your employer's program sets the exact equipment.
In the questionnaire you select the respirator you will use: disposable N95-type, half-facepiece, full-facepiece, or SCBA. If your job uses a supplied-air blasting hood or a powered air-purifying respirator (PAPR), check with your employer before you buy.

Yes, when the respirator is required by the employer. OSHA 1910.134 requires a medical evaluation before fit testing or use, and that includes respirators worn for welding fume.
No. Medical clearance confirms you can safely wear a respirator; a fit test checks that a specific tight-fitting respirator seals to your face. You need the clearance first.
