Short answer. Yes, on both counts. The Labor Code requires every employer to keep first-aid medicines and equipment in the establishment, scaled to the nature and conditions of the work, and separately to take steps to train enough employees in first-aid treatment. Neither duty is optional.
What the law says
Every employer shall keep in his establishment such first-aid medicines and equipment as the nature and conditions of work may require
Labor Code, Article 156 — First-Aid Medicines And Training. Read the full provision →
Two duties, not one
The article does two separate things in three sentences. First, it obliges the employer to stock first-aid medicines and equipment on the premises. Second, and independently, it says the employer shall take steps for the training of a sufficient number of employees in first-aid treatment. A workplace with a well-stocked cabinet that nobody is trained to open has satisfied only half the provision. Conversely, sending one person on a course while keeping nothing on site fails the other half.
How much is enough is set by the work, not by the employer's budget
The standard is such first-aid medicines and equipment as the nature and conditions of work may require. That is a sliding scale keyed to actual risk: a workplace using heavy machinery, heat, chemicals, or heights plainly requires more than a small office, and a site with staff spread across shifts or floors needs coverage that reaches all of them. The same logic governs training — a sufficient number means enough trained people that someone competent is actually present when an injury happens, including on night shifts.
The detail is filled in by regulation
The article does not itself list contents or hours; it says the duty runs in accordance with such regulations as the Department of Labor and Employment shall prescribe. So the concrete specifications for a given workplace come from the occupational safety and health rules that apply to it, and those turn on the establishment's size and hazard classification. If you are trying to work out what your own workplace should have, the article establishes that a duty exists and the applicable regulations supply the quantities.
If your workplace has neither
Note what is missing and when you noticed it, and raise it in writing with your supervisor or the safety committee if there is one — a dated request is worth far more later than a remembered conversation. If an injury has already occurred and there were no supplies or trained responder on hand, record that fact immediately alongside the incident details. Safety complaints are handled through the labour department's inspection machinery rather than as a private claim, so getting the facts documented early is the practical first step.
