Short answer. Yes. Article 156 requires every employer to keep first-aid medicines and equipment in the establishment as the nature and conditions of the work require, following regulations set by the Department of Labor and Employment, and to train a sufficient number of employees in first-aid treatment.
What the law says
First-aid treatment. Every employer shall keep in his establishment such first-aid medicines and equipment as the nature and conditions of work may require, in accordance with such regulations as the Department of Labor and Employment shall prescribe. The employer shall take steps for the training of a sufficient number of employees in first-aid treatment.

The duty applies to "every employer"
Article 156 opens with a blanket statement: every employer shall keep in his establishment such first-aid medicines and equipment as the nature and conditions of work may require. Unlike some other Labor Code provisions that are limited to establishments of a certain kind or size, this article's basic obligation is not qualified by the type of business — every employer is covered by the requirement to maintain first-aid supplies.
What "as the nature and conditions of work may require" means
The article does not fix a single, uniform kit that applies identically to every workplace. It ties the required medicines and equipment to the nature and conditions of work, meaning what is adequate depends on the kind of hazards present on the job. A workplace involving heavier physical or mechanical risk would reasonably need to keep a different set of first-aid supplies on hand than an ordinary office setting, and the specifics of what is required are filled in by regulations the Department of Labor and Employment is authorized to prescribe.
Training employees is a separate, express requirement
Beyond stocking supplies, Article 156 separately requires the employer to take steps for the training of a sufficient number of employees in first-aid treatment. This is not optional or left to the employer's discretion about whether training matters; the article treats having supplies on hand and having people trained to use them as two distinct obligations that both need to be satisfied.
What the article does not spell out
Article 156 does not itself list a minimum inventory of items, specify how many employees must be trained relative to workforce size, or describe enforcement procedures. Those particulars are left to the regulations the Department of Labor and Employment is authorized to issue under this article, so this page will not invent numbers or a checklist that the text itself does not provide. Article 156's first-aid duty is also distinct from the separate requirement for an emergency hospital or dental clinic that other provisions in this chapter impose — a requirement that, under Article 158, does not apply where an accessible hospital or dental clinic already reserves beds and facilities for the employer's employees. Keeping first-aid medicines and training staff does not by itself satisfy that separate obligation.
