Logo for transportation safety company/ specializing in hazardous materials.

C'est ce que SAFETY4HAZARDS, LLC recherchait dans leur logo design

Looking for a catchy logo for a transportation safety company. I would like to have two parts. 1. Icon like portion - abbreviation of the name and a hazmat placard implemented in it. 2. The full company name written underneath.
The logo should bring attention but should not be too crowded.
Attached below are the different variations of hazmat placards.
The function of this company is to help transportation companies to be in compliance with the laws and the regulations for transporting hazardous materials in the USA. We need a logo that is serious, that relates to the field the company is in. The importance of having a hazmat placard incorporated in the logo is because the first thing that comes to ones mind when thinking of hazmat is the placard. It also symbolizes attention/caution.
