Cherry Hill hazmat response contained at Keystone on Hollywood Avenue

Crews responded just after midnight Tuesday, June 30, 2026, to a hazmat situation at Keystone Research & Pharmaceutical in Cherry Hill’s 600 block of Hollywood Avenue, according to 6abc Philadelphia. Early reporting said responders found a haze and a strong odor and were told the incident may have involved a chemical reaction. The building was empty when crews arrived.

The practical takeaway for nearby residents and businesses is that this was an overnight response at a commercial site, and the early reports describe it as contained. The cause has not been fully explained in the initial reporting, so the incident should still be treated as an active investigation rather than a final conclusion.

Cherry Hill Township’s public-safety pages show the fire department and emergency management functions under the township’s public-safety umbrella, and the township says Fire Station 6 houses a specialized HazMat unit. Federal facility records also tie a Keystone Industries site to 616 Hollywood Ave., which matches the location described in the initial report.

For now, the main question is what investigators determine next and whether the site needs any follow-up ventilation, cleanup, or access restrictions before normal operations resume.
