JSL,
Safety is all about reducing the risk of exposure to hazard. You have identified a probably risk factor that could expose pax to hazard through 'weak' SOPs. If I were you I would submit a report to the Safety Manager. If you subsequently incur the wrath etc, the submit a second report on how company culture impedes effective hazard analysis and subsequent risk management - a fundamental aspect of SMS.
It is amazing how little attention is paid to cabin crew views when designing SOPs.
