**The label should be as short as possible without creating ambiguity.** In many workplaces, the employer is required (OSHA, ISO, FDA, etc.) to train anyone who would be working in a particular area with the hazards of the environment and the equipment. The label acts as a reminder (as well as a legal obligation). Everyone in that lab knows lighting a flame near the hydrogen hood is a bad idea. Anyone entering that lab should require safety training. If the labels you used as examples are positions such that there is no ambiguity as to which system has to be turned off or which cover can't be opened, then clarify. If it's clear, don't add additional wording. If the label is on the wall, then, yes, it should specify you're talking about the spectrophotometer with the yellow cover. If you are working in a small business that is not government regulated, then the need for more explicit labels may be required.
