I have been assigned a task to add sprinkler coverage to a walk-in cooler and freezer. These walk-in boxes have been moved from one facility (not sprinkled) to another facility (fully sprinkled). There isn't much room to work from above so my question is are dry sidewall sprinklers acceptable for installation?
